BTS_Tests: send SACCH blocks in TC_rsl_ms_pwr_dyn_{up,max,ass_updown}

We used to rely on trxcon sendig dummy RR Measurement Reports and
patching the L1 SACCH Header with the configured MS Power Level
and Timing Advance values.  Since recently, the following testcases
started to fail because trxcon does not patch dummy MRs anymore:

* TC_rsl_ms_pwr_dyn_ass_updown,
* TC_rsl_ms_pwr_dyn_max, and
* TC_rsl_ms_pwr_dyn_up.

Do not rely on dummy MRs, send SACCH blocks with the expected
MS Power Level and Timing Advance values from the testsuites.

f_send_meas_rep() internally uses:

* g_pars.l1_pars.ms_power_level, and
* g_pars.l1_pars.ms_actual_ta.
