XArray: Include bitmap.h from xarray.h
xas_find_chunk() calls find_next_bit(), which is defined in find.h,
included from bitmap.h. Inside the kernel, this isn't a problem because
bitmap.h is included from cpumask.h which is dragged in (eventually)
by gfp.h. When building the test-suite, that doesn't happen, so we need
to include bitmap.h explicitly.
