The possible values for `multipathtcp` are now:
- "0": disable MPTCP on dialers and listeners by default
- "1": enable MPTCP on dialers and listeners by default
- "2": enable MPTCP on listeners only by default
- "3": enable MPTCP on dialers only by default

For Go 1.24, it now defaults to multipathtcp="2", thus
enabled by default on listeners. Using multipathtcp="0" reverts to the
pre-Go 1.24 behavior.
