[PATCH v2] Remove trailing slash after remove-suffix

[cgit at cryptocrack.de (Lukas Fleischer)]

When removing the ".git" suffix of a non-bare repository, also remove
the trailing slash for compatibility with cgit_repobasename().

The previous version had a flaw (bogus pointer if there is no ".git"
suffix). This one is much more readable add should be applied on top of
the Git 2.2.0 patch (which adds strip_suffix() and strip_suffix_mem()).
