rL329226: [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.
