sysinfo.c: SI1 is optional; Send SI2 at TC=0 if no SI1 exists
SI1 is only required if frequency hopping is used or if NCH is used. So it's optional. If OsmoBTS has no SI1 configured, it will transmit the empty SI1 buffer at TC=0, and as a result no valid SI will be broadcast at TC=0. Change-Id: I41ab885c00e943199b2e939e98f30e267ecffbee Closes: OS#3051
