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.

  $ hg init
  $ echo a > a
  $ hg ci -Ama
  adding a

  $ echo b > b
  $ hg branch b
  marked working directory as branch b
  $ hg ci -Amb
  adding b

  $ hg co -C 0
  0 files updated, 0 files merged, 1 files removed, 0 files unresolved

Fast-forward:

  $ hg merge b
  1 files updated, 0 files merged, 0 files removed, 0 files unresolved
  (branch merge, don't forget to commit)
  $ hg ci -Ammerge

Bogus fast-forward should fail:

  $ hg merge b
  abort: merging with a working directory ancestor has no effect
