tests: allow "git version" test to pass on arbitrary git versions

Sometimes people run development versions of git.
On these versions, "git version" returns, for example:

git version 1.5.4.rc2.1105.gfc5f2

The test_it_executes_git_to_shell_and_returns_result
testcase was updated to accept these versions of git.
