It seems that setting a fixed value to PYTHONHASHSEED guarantees that
the bytecodes are generated consistently/in a reproducible manner.
Hopefully, this is the last bit to make Python3 build reproducible.
Tested this locally on a few files [that were not reproducible without
this change].
The PYTHONHASHSEED is only assigned to the host Python/Python3 during
compilation of byte-codes [from python source].

The only difference just a parameter for Python3
[ -b to compile bytecodes in legacy mode ].
No need to keep 2 almost identical files now
that they're exported.
I'm a bit scared of that param, since it may get
removed at some point.
But let's see until then.

Since `lang/python` is it's own folder of Python packages
(for both Python 2 & 3), and these build rules are needed
in a lot of packages [especially Python packages],
putting them here makes sense architecturally,
to be shared.
This also helps get rid of the `include_mk` construct
which relies on OpenWrt core to provide, and seems
like a broken design idea that has persisted for a while.
Reason is: it requires that Python 2/3 be built to provide
these mk files for other Python packages,
which seems like a bad idea.
Long-term, there could be an issue where some other feeds
would require these mk files [e.g. telephony] for
some Python packages.
We'll see how we handle this a bit later.
For now we limit this to this feed.

This reverts commits 4333d1dcbf and
074d2863be, making Python packages
discoverable again by pkg_resources.
Fixes#5361.

That way some python packages can choose
to keep their egg-info dirs, if they want to, or they're needed.

Depending on execution order the `python-package-install.sh`
script would return a non-zero err code.
So, this enforces that all commands in the script
don't fail (via the `set -e` directive).

I admit this may be be a bit aggressive, but the lang
folder is getting cluttered/filled up with Python, PHP, Perl,
Ruby, etc. packages.
Makes sense to try to group them into per-lang folders.
I took the Pythons.

Well, they're not yet compiled, but in the next commit
they should be.
People have been complaining [citation needed] to me
via email or via Github that Python's performance is crap
because it packages sources directly and they're not compiled.
And Python has to compile the sources on each run, and
on-the-fly.
Allowing compilation caching is also a no-no, because
I'll get complaints that the flash storage fills up
whenever a Python app runs.
So, to give the user a choice, the new de-facto packaging
for Python packages will be:
* ship compiled + [ preferably ] optimized files
* package sources separately
The problem is that this doubles the number of packages
in LEDE/OpenWrt, but build-times should not suffer a big
hit, since the compilation is done once, and the
install phase should not be too intensive.
Oh, and people don't need ship source packages if
they don't want to.
To do that, a packager needs to just call
`$(eval $(call BuildPackage,python-<package>-src))`
The `python-` prefix is important.
