print_timespec.h: parametrize TIMESPEC_T.tv_nsec

This is going to be used to implement a parser of SO_TIMESTAMP_NEW
control message.

* print_timespec.h [!TIMESPEC_NSEC] (TIMESPEC_NSEC): Define to tv_sec.
(TIMESPEC_TO_SEC_NSEC, timespec_fmt, print_timespec_t_utime): Use
TIMESPEC_NSEC instead of tv_sec.
