run-tests: include 'start' and 'end' in --time output

This is useful information to understand what is taking time in tests. Both are
included because I can see myself sorting this output using shell script. Having
both data makes it much easier than extracting 'start'+'real'.

This file tests the behavior of run-tests.py itself.

Avoid interference from actual test env:

  $ unset HGTEST_JOBS
  $ unset HGTEST_TIMEOUT
  $ unset HGTEST_PORT
  $ unset HGTEST_SHELL

it's actually the same test being reported for failure twice.
