revsetbenchmark: automatically finds the perf extension
Before this changeset, you had to stand in the root of the mercurial repo to run
the `revsetbenchmark.py` script. Otherwise, the perf extension would not be
found a `./contrib/perf.py` and the script would crash in panic.
We now figure out the contrib directory from the location of this script. This
makes it possible to run the script from other location that the mercurial repo
root (but you still need to be in the core mercurial repository)
