fundingmanager: use minHtlc from initFundingMsg

Browse Source 
This commit makes the fundingmanager read the minHtlc
field of the initFundingMsg, and add it to the reservation
as this node's htlc_minimum_msat for the open_channel
message. If the field is not specified in the initFundingMsg,
the default value found in the DefaultRoutingPolicy will
be used.
