bts: f_est_dchan(): populate UL SACCH cache

This ensures that UL SACCH blocks always contain the expected content and a proper L1 SACCH header, rather than the dummy measurement report hard-coded in trxcon/firmware. As a result, the BTS receives consistent and realistic UL SACCH from the very beginning.
