[Bernhard Voelker]

GCC-7.2.1 complains:
  ../gl/lib/stat-time.h:215:47: error: unused parameter 'st' \
  [-Werror=unused-parameter]
   stat_time_normalize (int result, struct stat *st)
                                                 ^~

* lib/stat-time.h (stat_time_normalize): Silence compiler regarding
the unused parameter ST.
