htlc_end: allow htlc_out to have 0 msatoshi.

Browse Source 
Such an htlc is invalid, and will be failed cleanly by our channeld
(which also checks that it meets the minimum amount), but it's
not the master's job to check it, and in fact, it asserts if we were
to try to pay or forward such a thing.

Fixes: #686
