Add eight time test files with packet dates in 2038, 2039, 2106 and 2107

Each capture file contains one packet.

time_2038.pcap:		   2038-01-01 00:00:00
time_2038_max.pcap:	   2038-01-19 03:14:07
time_2038_overflow.pcap:   2038-01-19 03:14:08
time_2039.pcap:		   2039-01-01 00:00:00
time_2106.pcap:		   2106-01-01 00:00:00
time_2106_max.pcap:	   2106-02-07 06:28:15
time_2106_overflow.pcapng: 2106-02-07 06:28:16
time_2107.pcapng:	   2107-01-01 00:00:00

The packet time when > 2038-01-19T03:14:07Z cannot be correctly printed
if time_t size is 32 bits (overflow).
Some tests are run only if HAVE_TIME_T_64 is set. it depends on the
output of "./tcpdump --time-t-size" (32 or 64).

A 32-bit unsigned time_t goes until 2106-02-07T06:28:15Z.
All values above require a pcapng file.
