BTS_Tests: fix TC_rsl_ms_pwr_dyn_{up,ass_down,max}: reply received SACCH L1H

As was explained in [1], until recently we relied on trxcon sendig
dummy RR Measurement Reports with patched L1 SACCH Header values.
Now trxcon does not patch it for us, so we need to send Uplink
SACCH blocks with the correct L1H ourselves.

Revision 2 of [1] was successfully tested and proved to fix the
above-mentioned testcases.  However during code review I was asked
to make the statements sending Uplink SACCH blocks self-explanatory.

In revision 3 of [1] I modified the code to call f_send_meas_rep(),
which was introduced in [2], which as stated in the commit message
is using g_pars.l1_pars.{ms_power_level,ms_actual_ta} instead of
the values from received L1H.  Of course this does not work.

Add and use f_send_meas_rep_l1h(), which allows to send the given L1H.
Take a chance to add a log() statement, so that we can see what we Tx.
