squashfs-tools aren't of much use without xz compression support
on OpenWrt, as we build kernel with squashfs supporting only xz.
Enabled support for xz compression by default.

Upstream backport.

All patches are not needed anymore. squashfs-tools has implemented them in
one way or another.

Converted to download release tarballs. This should work better to get
notified of a newer release.

Also adds support for ZSTD compression:

squashfs-tools does not provide tar-balls.
It looks like a good time to pull a newer version
that obsoletes a few accepted patches.

Unsquashfs was segfaulting.  When examining in gdb the stack was corrupt.
I found that converting the variable length arrays to malloc caused the
stack corruption to not happen and the segfault went away.  This is due to
the musl pthread stack size being 80k by default.  So the chance of a stack
overflow is high.

fix Makefile chmod (644)
replace MD5SUM with HASH
add PKG_MIRROR_HASH when PKG_SOURCE_PROTO:=git

(PKG_SOURCE_PROTO:=svn tarballs are not reproducible for now)

This fixes build errors with external toolchains that don't
automatically search for headers in STAGING_DIR:

Part of a wider housekeeping effort on the packages repository.

Otherwise it will pull all compression libraries to install
(on newly configured targets) when maybe 1 or 2 are needed.

Seems that this issue with squashfs-tools was fixed by the guys
at openembedded.
See patch here:
https://github.com/openembedded/openembedded-core/blob/master/meta/recipes-devtools/squashfs-tools/squashfs-tools/0001-mksquashfs.c-get-inline-functions-work-with-C99.patch

I think in my case, this issue appeared because I wrote the Makefile
some time ago and it worked, then when I did the PR for it,
it wasn't working anymore, and I assumed it was still working.
