selftests/bpf: align build_id test mapping to 64K page size 

Some architectures require mappings to be aligned to the system page size.
The build_id selftest currently uses a smaller alignment, which can result
in madvise operations executing on a different page than intended.

Increase the mapping alignment to 64K so the buffer is page-aligned on
all supported architectures.
