libselinux incorrectly initializes the host platform's arch using uname -m,
which actually returns the build platform's arch. This results in an invalid
compile flag (-mno-tls-direct-seg-refs) when compiling from x86_32.
So we need to set the host arch variable explicitly.

pkgconfig was aliased in 2018, however, it remained in
all-packages.nix due to its wide usage. This cleans
up the remaining references to pkgs.pkgsconfig and
moves the entry to aliases.nix.
python3Packages.pkgconfig remained unchanged because
it's the canonical name of the upstream package
on pypi.
libselinux needs native python to compute the installation prefix.
Swig generates the c code for the extension and needs python.h at compile,
so we put python into buildInputs
Avoid this warning (which is in turn an error via -Werror):
````
avc_internal.c: In function 'avc_netlink_receive':
avc_internal.c:105:25: error: cast increases required alignment of target type [-Werror=cast-align]
struct nlmsghdr *nlh = (struct nlmsghdr *)buf;
^
````
The code allocates abuffer with "__attribute__ ((aligned))",
then passes it via a 'char*' parameter, which is then finally cast,
causing the warning. So the code is ok but compiler is not smart
enough to see it.
It seems that -Wcast-align is a no-op on x86, so this shows up on ARM
only.
The reason this is optional is because we might want to use it for bootstrapping
in some constellations. And we really don't want whole lot of dependencies in
those situations.

fetchurl will try to download from that location automatically. So
we can keep the original URLs.
