BTS_Tests: use 0.0 as default for mp_ipa_up_delay

The module parameter mp_ipa_up_delay ads a delay after the ipa bring up.
This is relevant for the tests with real BTS hardware, but it is not
relavent for the regular TTCN3 tests.

Lets set the default to 0.0, since the delay caused problems with
TC_rsl_ms_pwr_ctrl and TC_si_sched_13_2bis_2ter_2quater.
