Make `test_adhoc` succeed from within a git checkout

The test currently only expects the literal `ansible` followed
by a semver in the first output line of `ansible --version`.
When running from within a git checkout, additional information
like the currently checkout branch are attached, which lets
the test fail. This commit allows arbitrary information to
follow the semver.
