tools/generate-wire.py: intuit tlvs field if a tlv type is mentioned.

Browse Source 
The modern style is to assert that all messages have tlvs, but many
are currently empty.  In particular,
c4c5a8e5fb30b1b99fa5bb0aba7d0b6b4c831ee5 added "update_add_htlc_tlvs"
without adding an explicit field of that type to "update_add_htlc".
