joinmarket: create bitcoind wallet

Browse Source 
Starting with 0.21.0, bitcoin no longer automatically creates and loads
a default wallet.
This was being ignored because of a JoinMarket issue [1] in CI builds prior
to this version. Now a watch-only Bitcoin Core wallet is created in ExecStartPost.

Starting with 0.21.0, bitcoind no longer automatically creates and loads a
default wallet named `wallet.dat` [1].
The joinmarket service now automatically creates a watch-only bitcoind wallet
(named by option `services.joinmarket.rpcWalletFile`) when creating a joinmarket wallet.
If you've used JoinMarket before, add the following to your configuration to
continue using the default `wallet.dat` wallet:
services.joinmarket.rpcWalletFile = null;
