profile: Set L2CAP IMTU for OBEX profile listeners
The default_settings entries for OBEX profiles (OPP, FTP, PBAP, MAS,
MNS) have no imtu field, so ext_start_servers() creates the L2CAP
listening socket without an explicit IMTU. This causes the socket to
advertise the L2CAP minimum of 672 bytes in L2CAP_CONFIGURATION_RSP,
limiting the peer's outgoing PDU size and degrading Rx throughput.
Add an imtu field to default_settings and set it to 32767 for all
OBEX profiles that use L2CAP. Copy the value in ext_set_defaults()
and apply it to the listening socket via bt_io_set() after
bt_io_listen() succeeds.
