bsc: Create minimal SI6 rest octets
In GSM R99 SI6 has mandatory SI6 rest octets and so far we did
not include them. Add minimal support to generate the right band
indicator.
Target a slightly older version of the SI6 rest octets as we neither
support MBMS nor Random bit stream but should include the band
indicator.
