lib/oe/reproducible: Fix error when no git HEAD

Browse Source 
Fixes an error that occurs when attempting to get the timestamp of the
latest commit when there is no HEAD in the git repository. The easiest
way to trigger this condition is to use the 'subdir=' option when
specifying a 'git://' SRC_URI.
