update btcwallet

I'm trying to compile with https://github.com/lightninglabs/lightning-terminal/blob/master/dev.Dockerfile using the LND_VERSION build arg.

litd master currently does not compile with lnd master. I get the following error:

I believe the problem is due to needing to update litd to account for lightningnetwork/lnd@641ff68 where btcwallet is updated.
