run-tests.py: execute hghave with same env vars as ones for actual tests

Before this patch, "run-tests.py" executes "hghave" process without
any modifications for environment variables, even though actual tests
are executed with LC_ALL, LANG and LANGUAGE explicitly assigned "C".

When "run-tests.py" is executed:

  - with non-"C" locale environment variables on any platforms, or

  - without any explicit locale environment setting on Windows
    (only for "outer-repo" feature using "hg root")

external commands indirectly executed by "hghave" may show translated
messages.

This causes incorrect "hghave" result and skipping tests, because some
regexp matching of "hghave" expect external commands to show
un-translated messages.

To prevent external commands from showing translated messages, this
patch makes "run-tests.py" execute "hghave" with same environment
variables as ones for actual tests.

This patch doesn't make "hghave" execute external commands forcibly
with LC_ALL, LANG and LANGUAGE explicitly assigned "C", because
changing "run-tests.py" is cheaper than changing "hghave":

  - "os.popen" should be replaced by "subprocess.Popen" or so, and
  - setting up environment variables should be newly added

Corrupt an hg repo with a pull started during an aborted commit
Create two repos, so that one of them can pull from the other one.

  $ hg init source
  $ cd source
  $ touch foo
  $ hg add foo
  $ hg ci -m 'add foo'
  $ hg clone . ../corrupted
  updating to branch default
  1 files updated, 0 files merged, 0 files removed, 0 files unresolved
  $ echo >> foo
  $ hg ci -m 'change foo'

Add a hook to wait 5 seconds and then abort the commit

  $ cd ../corrupted
  $ echo "[hooks]" >> .hg/hgrc
  $ echo "pretxncommit = sh -c 'sleep 5; exit 1'" >> .hg/hgrc

start a commit...

  $ touch bar
  $ hg add bar
  $ hg ci -m 'add bar' &

... and start a pull while the commit is still running

  $ sleep 1
  $ hg pull ../source 2>/dev/null
  pulling from ../source
  transaction abort!
  rollback completed
