This is required to start osmo-pcu after osmo-bts is already setup and
activated. Otherwise osmo-pcu ends after connecting to socket with:
"pcu_l1_if.cpp:416 BTS not available"

Otherwise osmo-bts stores the socket file in /tmp. If an earlier
instance doesn't finish cleanly, the file is left there and a new
instance will fail to start because it cannot create a new socket file
in the same place.
