[PATCH v2] transport.c: mark push status strings for translation

["Nguyễn Thái Ngọc Duy" <pclouds@gmail.com>]

Mark strings like "[up to date]" passed to print_ref_status() for
translation with N_() instead of _() so they can remain untranslated
in porcelain mode.

While at there, mark some error strings in git push for translation
too.
