tests: de-flake test-narrow-share.t by making dirstate predictable

test-narrow-share.t was sometimes (~0.5% on my machine) failing like this:

     A d3/g
     $ hg -R main debugdirstate --no-dates
     n 644          2 set                 d1/f
  -  n 644          2 unset               d3/f

     n 644          2 set                 d7/f

The timestamp for d3/f would get set if it was determined at some
point that it was clean. That check is usually done when the user runs
`hg st`. We don't do that before the failure in the test case, but it
happens at the end of the `hg clone` call. So if the file system's
time happens to roll over after the clone's working copy has been
written, but before its (final) dirstate has been written, we can end
up with a set timestamp there.

This patch makes it consistent by sleeping for 2 seconds so the
timestamp gets reliably set.
