clock: Use PRIi64 instead of G_GINT64_FORMAT
This is supported by gettext. See https://www.gnu.org/software/gettext/manual/html_node/Preparing-Strings.html and https://savannah.gnu.org/bugs/index.php?66313
This then turns up as
msgid "%<PRIi64> minute ago"
msgid_plural "%<PRIi64> minutes ago"
in the message catalog.
Closes: #948 (closed)
