Drop jemalloc specific smartRealloc integration

Summary:
This was added several jemalloc versions ago, and is no longer a win.

From microbenches in folly/test, this codepath is successful less than .5% of the time.

There are a handful of other places directly using this (fbvector, IOBuf, ThreadLocal),
but should probably change them individually.
