osmo-ttcn3-hacks adds configuration of the CTRL interface in
I502b4891e6720ae2fb251c03542f707880a6f728. We need proper IP addresses here for
the f_ipa_ctrl_start() to work.
WARNING: This commit has to be merged "at the same time" as
I502b4891e6720ae2fb251c03542f707880a6f728 or the jenkins ttcn3-bts-tests will
fail.
a) if we want to set a modulepar mp_ctrl_ip here, it needs to be added to
osmo-ttcn3-hacks.
b) if we have the f_ipa_ctrl_start() in osmo-ttcn3-hacks, we need to configure
the proper IP and bind interface here, or all tests will fail because
f_ipa_ctrl_start() cannot connect.
