gettime: port better to non-POSIX C2x
C2x requires a function timespec_get; prefer that to
gettimeofday, since it has better resolution.
* lib/gettime.c (gettime): Prefer timespec_get to gettimeofday.
* m4/gettime.m4 (gl_GETTIME): Check for timespec_get.
Omit a check for gettimeofday; not needed because
the gettime module depends on the gettimeofday module.
