backup: fix issue when the backup end up in a different directory

Because of store encoding, we might end up with the backup in a different
directory than the initial copy (for example if the backup path make it cross
the 120 char limit).

This can create crash, especially since 6.4 where backup are used during revlog
split.

Making sure the directory exists fixes these crash We added a test covering this
case.

Strictly speaking, this has always been broken, however the new code in 6.4
triggers it more easily.

#require no-windows no-rhg

XXX-RHG this test hangs if `hg` is really `rhg`. This was hidden by the use of
`alias hg=rhg` by run-tests.py. With such alias removed, this test is revealed
buggy. This need to be resolved sooner than later.

Kludge to emulate timeout(1) which is not generally available.
