Skip blame libgit2 test if not in libgit2 repo

One blame test replies on being run from within the libgit2
repository to leverage having a longer history to play with, but
some bundled versions of libgit2 don't have the whole libgit2
history.  This just skips that test if the repository can't be
opened.
