bmalloc DebugHeap should not crash in low-memory conditions on Linux
https://bugs.webkit.org/show_bug.cgi?id=252053
Reviewed by Yusuke Suzuki.
`posix_memalign` may not initialize the result pointer if it fails on Linux
[1].
If we don't initialize the result ourselves, this manifests as later
segfaults/bus errors/bizarre behavior as we get a completely bogus result
that
can point basically anywhere.
