git: local_nick: handle trailing or redundant '/' in git_dir

Some cgit configs use trailing slashes in pathnames
which we preserve internally.

Before this change, trailing slashes in cgit config files
was causing ViewVCS (SolverGit) output to show up as "???"
for coderepos without cgitUrl configured.
