bridge: mdb: print protocol when available

Print the mdb entry's protocol (i.e. who added it)  when it's available if
the user requested to show details (-d). Currently the only possible
values are RTPROT_STATIC (user-space added) or RTPROT_KERNEL
(automatically added by kernel). The value is kernel controlled.
