bsc: Test CSFB "Fast Return" in new TC_chan_rel_hard_clear_csfb
When a MSC releases a connection using the BSSMAP CLEAR CMD, it can
specify that this call was part of CSFB.
The BSC is then supposed to add a special IE to the RR RELEASE
message which will help the phone to switch back to LTE as soon
as possible.
This commit adds a new test case testing for exactly that behavior.
The test does *not* verify if the EARFCN information contained is
actually correct, only that the IE is present in the RR RELEASE.
