python-native, python3-native: remove the use of exported HOST_SYS and BUILD_SYS variables

The code that utilized them was superseded by the code (in the same patch!)
that is utilizing STAGING_LIBDIR/STAGING_INCDIR, and wasn't correct in the
first place as HOST_SYS is not necessarily the same as the sysroot directory
name.
