[Sanitizers] ASan and LSan allocator set errno on failure.
Summary:
Set proper errno code on alloction failures and change some
implementations to satisfy their man-specified requirements:
LSan: valloc and memalign
ASan: pvalloc, memalign and posix_memalign
Changing both allocators in one patch since LSan depends on ASan allocator in some configurations.
