elf: Remove excessive p_align check on PT_LOAD segments [BZ #28688]
removed the p_align check against the page size. It caused the loader
error or crash on elf/tst-p_align3 when loading elf/tst-p_alignmod3.so,
which has the invalid p_align in PT_LOAD segments, added by
commit d8d94863ef125a392b929732b37e07dc927fbcd1

The loader failure caused by a negative length passed to __mprotect is
random, depending on architecture and toolchain. Update _dl_map_segments
to detect invalid holes. This fixes BZ #28838.
