flags: introduce explicit testing for merging change to exec flag

It turns out that we do not seems to test the simple case for merging exec flag
changes. More advanced case are test (merging exec flag without a common
ancestors, merging with a symlink, etc…) but not the basic.

We are about introduce various fixes to merging flag change across renames,
having  the most basic case tested first seems useful.

note: We are only testing "adding" an exec flag here, not removing it. We
introduce basic test on stable and will consolidate them on default.

In the merge below, the file "foo" has the same contents in both
parents, but if we look at the file-level history, we'll notice that
the version in p1 is an ancestor of the version in p2. This test makes
sure that we'll use the version from p2 in the manifest of the merge
revision.

  $ echo foo > foo
  $ hg ci -qAm 'add foo'
