giscanner: Replace repr format usage with string formatter

Replace occurances of "%r" (repr) in format strings where the intended
behaviour is to output a quoted string "'foo'" with explicit usage
of "'%s'". This is needed to move the codebase to unicode literals
in order to upgrade to Python 3. Python 2 unicode strings are expanded
with repr formatting prefixed with a "u" as in "u'foo'" which causes
failures for various text formatting scenarios.
