ubridge: default the control transport to unix
Switch ubridge_control_transport from tcp (-H) to unix (-U), the
AF_UNIX + SO_PEERCRED channel recommended on Linux for kernel-level
peer authentication. tcp is retained as an opt-in for backward
compatibility. Existing deployments that set the key explicitly are
unaffected; only fresh installs / unset keys pick up the new default.
