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.
