Remove best fit for extent selection.
A jemalloc user reported that the best fit selection is causing them
a memory leak. This code has been completely removed from the next
release of jemalloc (5.2.0), so remove it since it doesn't have any
real benefit.
See https://github.com/jemalloc/jemalloc/issues/1454
Running the memory dumps, removing best fit appears to be a win: it is
slightly faster and has the same PSS/VA.
Bug: 128697497
Test: Ran jemalloc unit tests.
Test: Ran memory dumps in 32 bit and 64 bit and observed that the PSS
Test: and VA stayed the same, while run time improved slightly.
