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?

  $ hg init
  $ echo a > a
  $ hg ci -Ama
  adding a

  $ echo b > b
  $ hg branch b
  marked working directory as branch b
  (branches are permanent and global, did you want a bookmark?)
  $ hg ci -Amb
  adding b

  $ hg co -C 0
  0 files updated, 0 files merged, 1 files removed, 0 files unresolved

Fast-forward:

  $ hg merge b
  1 files updated, 0 files merged, 0 files removed, 0 files unresolved
  (branch merge, don't forget to commit)
  $ hg ci -Ammerge

Bogus fast-forward should fail:

  $ hg merge b
  abort: merging with a working directory ancestor has no effect
  [255]

Even with strange revset (issue4465)

  $ hg merge ::.
  abort: merging with a working directory ancestor has no effect
