As described in https://osmocom.org/issues/2380 and related gerrit
patch https://gerrit.osmocom.org/#/c/3306 the config files currently
contain timers with a 'zero' value, leading to issues.
The config file templates used in osmo-gsm-tester suffer actually
from exactly the same issue: They basically contain values that were
written back to the file based on the default initialization in libbsc,
which unfortunately was zero in some cases.
Let's remove those values, they are the (bad) default anyway.
libbsc patches in the pipeline will introduce reasonable defaults
and forbid the use of zero for timers.

Otherwise 127.0.0.1 was being used and we want all interfaces for a
specific osmo-bsc instance to use the same IP
