buildhistory: fix the check for existence of a git repo

Previously, in order to determine the existence of an already
initialized Git repository we checked if a directory named '.git' was
present in the buildhistory dir. However, e.g. in the case of git
submodules '.git' may also be a regular file referencing some other
location which was causing unwanted behavior. This patch changes
buildhistory.bbclass to check for any file named '.git' which fixes
these problems.
