test/func/malloc: posix_memalign vs. size_t

Browse Source 
posix_memalign requires that the alignment parameter be a multiple of
sizeof(uintptr_t), but the test begins with alignments as small as
sizeof(size_t).  While those are very likely the same value out in the
wild right now, they're not on CHERI.

Begin the test loop at sizeof(uintptr_t) and add a test that a request
for a reasonable amount of memory but with an alignment of
sizeof(uintptr_t)/2 fails with EINVAL.
