Change Solver() output for WITNESS_V1_TAPROOT
This is just a small simplification to prepare for the follow-up instruction
of a CTxDestination variant for taproot outputs.
In the old code, WITNESS_V1_TAPROOT and WITNESS_UNKNOWN both produced
{version, program} as Solver() output. Change this so that WITNESS_V1_TAPROOT
produces just {program}, like WITNESS_V0_* do.
