go: replace lightning-onion with fork

Use fork github.com/gijswijs/lightning-onion at commit fac332540872 to
include onion-messaging support before the upstream PR is merged.

This temporary replace in go.mod ensures compatibility with the current
module path while allowing local development and CI to build with the
new functionality.
