test-hardlinks: add testcase for repo copied with 'cp -al'
This patch adds a case to test-hardlinks.t which demonstrates that
hardlinks in the working directory are broken up (using 'hg update').
Motivation for this patch:
'hg help clone' shows copying repositories *and* the working directory
using 'cp -al', creating hardlinks in the *working directory* too (not
just in the store).
Note that we can't use 'cp -al' since for example MacOS X doesn't
support these options on cp. I'm thus using the same trick as in
test-hardlinks-safety.t for creating hardlinks in the working dir.
