common/bts.c: bts_supports_cm(): take care about GSM48_CMODE_SIGN
At the moment, bts_supports_cm() is only called on reception of RSL Channel MODE MODIFY from the BSC. The idea is to check whether the indicated RSL channel mode is supported by a BTS model. RSL Channel MODE MODIFY message may indicate a channel in signalling mode, i.e. GSM48_CMODE_SIGN, which has always been rejected so far. Let's assume that signalling is always supported, as there is no special BTS_FEAT_* definition to check that. This change should make BTS_Tests.TC_rsl_modify_encr pass.
