bsc_vty: improve manual activation of lchans (debug / labtest)
The VTY already has a method available to activate lchans manually, however, this method does not support proper activation of signalling channels. Also additional commands to activate multiple lchans at once are helpful to make labtesting simpler and more efficient. Change-Id: I66b874736c8c456eb82ccc26d5209987d8ed706c Related: SYS#4910
