Bump btcd version in btcutil package

[darioush]

Hi,

When I depend on github.com/btcsuite/btcd/btcutil v1.1.1 (but not github.com/btcsuite/btcd), I end up with the
v0.22.0-beta.0.20220111032746-97732e52810c version as a dependency in my go.sum.

This would normally be fine but it seems you have recently fixed an ambiguous import issue (#1839):

github.com/btcsuite/btcd/chaincfg/chainhash: ambiguous import: found package github.com/btcsuite/btcd/chaincfg/chainhash in multiple modules:
	github.com/btcsuite/btcd v0.21.0-beta (/Users/darioush.jalali/go/pkg/mod/github.com/btcsuite/btcd@v0.21.0-beta/chaincfg/chainhash)
	github.com/btcsuite/btcd/chaincfg/chainhash v1.0.1 (/Users/darioush.jalali/go/pkg/mod/github.com/btcsuite/btcd/chaincfg/chainhash@v1.0.1)

So it would be beneficial to bump the version in the sub-module past your fix.
Apologies in advance if you would have preferred an issue instead of a PR. Thanks :)

Also noticed #1825 may fix this.
