configure.ac: check 'tv_nsec' field in 'struct stat'
Detect 'tv_nsec' field in 'struct stat' and set Makefile variable NO_NSEC appropriately. A side-effect of the above detection is that we also determine whether 'stat.st_mtimespec' is available, so, as a bonus, set the Makefile variable USE_ST_TIMESPEC, as well.
