[asan] Fix aligned_alloc test case

[asan] Fix aligned_alloc test case

Summary:
Under some circumstances (that I haven't dug further into), the first stack
frame for the test looks like:
`#0 0x4e6038 in __interceptor_memalign.localalias.1 ...compiler-rt/lib/asan/asan_malloc_linux.cc:113`
which isn't matched by the current CHECK.

Expand the CHECK to match aligned_alloc or memalign. Hopefully this should fix
the PowerPC issue as well, otherwise we'll bring back the FIXME.
