bsc: Increase T3101 in osmo-bsc.cfg
Test BSC_Tests.TC_ho_during_lcs_loc_req sporafically failed due to ttcn3
taking >2s to transmit the Handover Complete and T3101 (3s by default)
firing before receiving it.
Increase it to give some more room and avoid sporadic failures.
See how 2nd RSL1.send() in as_handover() is delayed for >2s:
