RADIUS: Redo the RFC 5580 test for Solaris. [skip ci]

The file tests/RADIUS-RFC5580.pcap had all NTP timestamps set to
0x01234567.89abcdef seconds since year 1900, which on Linux and FreeBSD
produced "19088743.537777777 (1900-08-09T22:25:43Z)", but on Solaris 10
produced "(unrepresentable)". Increment Sighting Time by 120 nominal
years worth of seconds and make Time-to-Live and Retention Expires 12
and 48 hours later respectively.
