hodec1: use same automatic FULL/SUBSET choice as in hodec2 

So far handover decision 1 uses the FULL or SUBSET TDMA measurements
across all measurement reports, depending on whether the last
measurement report indicates that DTX is in use or not.

Handover decision 2 since recently uses TDMA_MEAS_SET_AUTO to choose for
each individual measurement report whether to use the FULL or the SUBSET
value, depending on each single report's DTX use flag.

Also switch handover decision 1 to heed every single report's DTX flag,
by simply using TDMA_MEAS_SET_AUTO, replacing the current decision.
