setup: add a test for running setup.py

`python3 -m pip install hg-evolve==9.2.0` currently fails, despite 9.2.0 being
the first beta py3 release, because of unicode issues with the version number.
`setup.py install` is a proxy test for pip install since it also suffers from
similar, however the test currently fails due to running setup.py from a
different directory to the one it is in.

Also add a test for `hg version -v` with evolve enabled since a naive first
solution for the pip issue was to just change `__version__` to a `u''` string,
but that busts version display in `version -v`, which isn't currently picked up
by tests.
