resolved: detect and warn other running mDNS stack

Previously, `SO_REUSEADDR` is set before `bind`-ing socket, Thus,
even if another mDNS stack (e.g. avahi) is running, `bind` always
success and we cannot detect the other stack.
By this commit, we first try to `bind` without `SO_REUSEADDR`,
and if it fails, show warning and retry with `SO_REUSEADDR`.
