Fix double-escaping of path segments on 1.6.1+

As of:

https://github.com/openSUSE/osc/commit/3f14cef53a853296d7f60bf7b14eb86615842cf9

osc.core.makeurl will escape path comonents itself, so calling pathname2url ends up double-escaping, resulting in 404 errors with filenames that have special characters.
