BTS_Tests: populate SACCH cache in f_TC_ms_pwr_ctrl_{constant,pf_ewma}
There is a time window between activation of a dedicated channel and
receipt of a L1CTL_DATA_REQ with the first RR Measurement Report, in
which the L1 may need to start transmission on Uplink SACCH.
In this case the L1 is using a dummy SACCH block with hard-coded L1
SACCH header values and hard-coded Measurement Results.
Until recently we relied on implementation specific behavior of trxcon
patching the L1 SACCH header in hard-coded dummy SACCH block. This
behavior was changed, so TC_ms_pwr_ctrl_{constant,pf_ewma} started to
fail. Let's properly populate the SACCH cache to fix these TCs.
