debugfsinfo: improve case-sensitive testing

Previously the case-sensitive test was for the current directory, and is
fragile with errors, and could remove a real file called ".debugfsinfo".

This patch improves the case-sensitive testing so it test the given path
using a unique temporary file, and does not crash on errors.

Test issue2761

  $ hg init

  $ touch to-be-deleted
  $ hg add
  adding to-be-deleted
  $ hg ci -m first
  $ echo a > to-be-deleted
  $ hg ci -m second
  $ rm to-be-deleted
  $ hg diff -r 0
