chainreg: use feerate estimator in regtest, simnet

Browse Source 
If feeurl is not provided and LND is running in bitcoind or btcd mode, use
fee estimator provided by bitcoind or btcd instead of using static fee estimator
(which always returns 50 sats/vbyte).

This enables simulating high feerate environment in regtest and simnet not only
via feeurl, but also by filling mempool with high feerate transactions, which is
closer to what happens in mainnet.

Also skip creating bitcoind or btcd fee estimator, if feeurl is provided. Before
LND logged both "Initializing bitcoind backed fee estimator" and "Using external
fee estimator" if running in bitcoind mode with feeurl provided, but actually
feeurl was used, so this is not a change of behavior.
