test: simplify test-amend.t to avoid race condition

Insted on relying on sleep, we could simply have the editor do the file change.
This remove the reliance on "sleep" and avoid test failing on heavy load
machine.

To test this, I reverted the code change in 5558e3437872 and the test started
failing again.

 Corner case of amend from issue6157:
 - working copy parent has a change to file `a`
 - working copy has the inverse change
 - we amend the working copy parent for files other than `a`
 hg used to include the changes to `a` anyway.
