xz: Enable BCJ filters on SPARC and 32-bit x86

The BCJ filters were meant to be enabled already on these archs, but the xz_wrap.sh script was buggy. Enabling the filters should give smaller kernel images. xz_wrap.sh will now use $SRCARCH instead of $ARCH to detect the architecture. That way it doesn't need to care about the subarchs (like i386 vs. x86_64) since the BCJ filters don't care either.
