tests: stop excluding the pycompat module from pyflakes
I assume this was skipped because of all of the py2 stuff causing a lot of spew.
The "unused" imports are left in place in case any 3rd party stuff is using it.
I don't care about most of it, but TortoiseHg uses `io` and `queue`, so
minimally I'd like to keep those.

'''measure performance of Mercurial commands Using ``hgperf`` instead of ``hg`` measures performance of the target Mercurial command. For example, the execution below measures performance of :hg:`heads --topo`:: $ hgperf heads --topo All command output via ``ui`` is suppressed, and just measurement result is displayed: see also "perf" extension in "contrib". Costs of processing before dispatching to the command function like below are not measured:: - parsing command line (e.g. option validity check) - reading configuration files in But ``pre-`` and ``post-`` hook invocation for the target command is measured, even though these are invoked before or after dispatching to the command function, because these may be required to repeat execution of the target command correctly.
