cvsimport: format commit timestamp ourselves without using strftime

Some implementations of strftime(3) lack support for "%z".  Also
there is no need for %s in git-cvsimport as the supplied time is
already in seconds since the epoch.

For %z, use the function get_tz_offset provided by Git.pm instead.
