run-tests.py: don't let hg run interactively in debug mode

In normal test mode stdin is closed and hg is thus not interactive. In --debug
mode stdin is inherited from the running console and to the tests, and hg could
thus wait in prompts when running on Windows.

See http://selenic.com/pipermail/mercurial-devel/2013-January/047548.html .

Instead set ui.interactive=False to make Mercurial non-interactive. Other
commands might still work differently in the --debug environment.

This should solve the problem with hg waiting for input but still make it
possible to add --debugger to hg in a test and run run-tests.py with --debug.

  $ hg init
  $ mkdir a
  $ echo a > a/b
  $ hg ci -Am m
  adding a/b

  $ hg rm a
  removing a/b (glob)
  $ hg ci -m m a

  $ mkdir a b
  $ echo a > a/b
  $ hg ci -Am m
  adding a/b

  $ hg rm a
  removing a/b (glob)
  $ cd b

Relative delete:

  $ hg ci -m m ../a

  $ cd ..
