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. Reviewed-by: Siddhesh Poyarekar <siddhesh@sourceware.org>
