s3:lib: add put_long_date_full_timespec()

put_long_date_full_timespec() will be used in the fileserver to marshall struct
timespec timestamps that are sent to the client. By using
full_timespec_to_nt_time() which supports tv_sec=0 and negative values, we can
return timestamps to clients with a date before the UNIX epoch.
