tests: use time.time() for relative start and stop times

os.times() does not work on Windows. This was resulting in the
test start, stop, and duration times being reported as 0.

This commit swaps in time.time() for wall clock measurements.

This isn't ideal, as time.time() is not monotonic. But Python 2.7
does not have a monotonic timer that works on Windows. So it is
the best we have which is trivially usable. And test times aren't
terribly important, so variances due to clock skew are arguably
acceptable.

====================================
Testing head checking code: Case C-2
====================================

Mercurial checks for the introduction of new heads on push. Evolution comes
into play to detect if existing branches on the server are being replaced by
some of the new one we push.

This case is part of a series of tests checking this behavior.

Category C: checking case were the branch is only partially obsoleted.
TestCase 1: 2 changeset branch, only the head is rewritten

.. old-state:
..
.. * 2 changeset branch
..
.. new-state:
..
.. * 1 new changesets branches superceeding only the head of the old one
.. * base of the old branch is still alive
..
.. expected-result:
..
.. * push denied
