python3-crc32c: set target platform via setup.cfg

Do not poke at build system for finding platform
platform is target specific and when cross compiling it should be
detected differently, in this case lets pass it via environment so that
it can be set in recipe

Looks like we're not the first to need to specify the target platform
[1]
when building this package.  According to upstream, we can just update
setup.cfg instead of patching setup.py.
