This removes Python-related build variants, and adds
PYTHON3_PKG_BUILD:=0 and minor build adjustments (where appropriate),
for non-Python packages. There should be no changes to build output.

This also updates some include paths for python3-package.mk and/or
python3-host.mk to be relative to the package Makefile.

Now that we only use kernel versions that support libgpiod,
we can remove the dependency on the kernel version.

This enables libgpiod to be used with linux 4.19.

libgpiod is a C library with corresponding tools for interacting
with the linux GPIO character device (gpiod stands for GPIO device).

Since linux 4.8 the GPIO sysfs interface is deprecated. User space should use
the character device instead. This library encapsulates the ioctl calls and
data structures behind a straightforward API.
