tests-subrepo-git: emit a different "pwned" message based on the test

Having a single "pwned" message which may or may not be emitted during the
tests for CVE-2016-3068 leads to extra confusion.  Allow each test to emit
a more detailed message based on what the expectations are.

In both cases, we expect a version of git which has had the vulnerability
plugged, as well as a version of mercurial which also knows about
GIT_ALLOW_PROTOCOL.  For the first test, we make sure GIT_ALLOW_PROTOCOL is
unset, meaning that the ext-protocol subrepo should be ignored; if it
isn't, there's either a problem with mercurial or the installed copy of
git.

For the second test, we explicitly allow ext-protocol subrepos, which means
that the subrepo will be accessed and a message emitted confirming that
this was, in fact, our intention.

Initial setup.

  $ hg init repo
  $ cd repo
  $ touch thefile
  $ hg ci -A -m 'Initial commit.'
  adding thefile

Create a tag.

  $ hg tag branchortag

Create a branch with the same name as the tag.

  $ hg branch branchortag
  marked working directory as branch branchortag
  (branches are permanent and global, did you want a bookmark?)
  $ hg ci -m 'Create a branch with the same name as a tag.'

This is what we have:

  $ hg log
