py3: teach run-tests.py to handle exe with spaces when --local isn't specified

This was the reason that no amount of quoting worked in test-hghave.t.

`os.popen()` needed to be swapped out because while the added quoting around
line 3124 worked on py3, it failed on py2.  See 38d51371792b.  The problem with
`os.system()` was wrongly splitting the command on the space in 'Program Files',
regardless of quoting.  It looks like there are a few other instances of
`os.system()` in core code, so presumably those should be replaced?
