stdlib: Let calendar:system_time_to_rfc3339() keep fractions
RFC3339 mentions in paragraph 5.1 that if certain conditions are
fulfilled, then sorting date and time strings results in a
time-ordered sequence. One of the conditions is that the strings must
have the same number of fractional second digits. This commits makes
sure this is indeed the case.
