Move MaybeReleaseAllocatorMemToOS to base

This CL refactors the calls to mallopt(M_PURGE) into
a base/utils.h function. It also makes it work consistently
on standalone builds using dlsym.
Unfortunately looks like we will have to put more workarounds
to deal with Scudo edge cases. See bug for discussion.
This CL will be used by the upcoming kallsyms symbolizer.
