mcheck.c doesn't take MALLOC_ALIGNMENT into account.

mcheck: Align struct hdr to MALLOC_ALIGNMENT bytes [BZ #28068]
1. Align struct hdr to MALLOC_ALIGNMENT bytes so that malloc hooks in
libmcheck align memory to MALLOC_ALIGNMENT bytes.
2. Remove tst-mallocalign1 from tests-exclude-mcheck for i386 and x32.
3. Add tst-pvalloc-fortify and tst-reallocarray to tests-exclude-mcheck
since they use malloc_usable_size (see BZ #22057).
This fixed BZ #28068.
