mptcp: add subtype matching

MPTCP multiplexes the various mptcp signalling data using the
first 4 bits of the mptcp option.

This allows to match on the mptcp subtype via:

   tcp option mptcp subtype 1

This misses delinearization support. mptcp subtype is the first tcp
option field that has a length of less than one byte.

Serialization processing will add a binop for this, but netlink
delinearization can't remove them, yet.

Also misses a new datatype/symbol table to allow to use mnemonics like
'mp_join' instead of raw numbers.

For this reason, no tests are added yet.
