tests: fix glob pattern for dynamic timer alignment
The number of space characters varies depending on the number of digits of the
timer, making some tests fail on slow machines in an unintended way:

#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.
