Make osmo-pcu wait for BTS to become available at start-up time.
After the PCU socket becomes available, the BTS might send an
INFO_IND message with the 'ACTIVE' flag cleared. If this happens,
do not exit immediately, but keep retrying until an INFO_IND
message with the 'ACTIVE' flag arrives.
Note that this change only affects behaviour at process start-up time.
If the BTS switches from active to inactive state then osmo-pcu will
still exit. If this behaviour should be changed as well it could be
done in a follow-up patch.
Tested against osom-bsc + osmo-bts-virtual.
