i18n: remote.c: mark error(...) messages for translation

Mark up the error(...) messages in remote.c for translation. The likes
of "unable to push to unqualified destination" are relatively big
parts of the UI, i.e. error messages shown when "git push" fails.

I don't think any of these are plumbing, an the entire test suite
passes when running the tests with GIT_GETTEXT_POISON=1 (after
building with GETTEXT_POISON).
