selftests/powerpc: Fix load_unaligned_zeropad build failure
This test is userspace code, but uses some kernel headers via symlinks,
and mocks other headers, in order to test load_unaligned_zeropad().
Currently the test fails to build with:
In file included from load_unaligned_zeropad.c:26:
word-at-a-time.h:7:10: fatal error: linux/bitops.h: No such file or directory
7 | #include <linux/bitops.h>
This is due to the recent changes to the kernel headers.
Fix it by symlinking the new wordpart.h, and creating an empty stub for
bitops.h which is all that's needed.
