migration: Support fd-based socket address in cpr_transfer_input
Extend cpr_transfer_input to handle SOCKET_ADDRESS_TYPE_FD alongside
SOCKET_ADDRESS_TYPE_UNIX. This change supports the use of pre-listened
socket file descriptors for cpr migration channels.
This change is particularly useful in qtest environments, where the
socket may be created externally and passed via fd.
