Cloning a tag-named branch introduced a supply chain attack vector,
because branch and tag contents might differ.
Now the hashed worktree always corresponds to the tag that is GPG-verified.
With electrs 0.9.0, option `--no-default-features` disables the `metrics`
feature, which brakes electrs option `--monitoring-addr`.
Fix this by removing `--no-default-features`, which is no longer needed
for dynamic linking in 0.9.0.
