get_route: fix path value contribution to include min htlc overpay

Previously, the fuzzer hit a debug panic because we wouldn't include the amount
overpaid to meet a last hop's min_htlc in the total collected paths value. We
now include this value and also penalize hops along the overpaying path to
ensure that it gets deprioritized in path selection.
