common/features: only support a single feature bitset.
This is mainly an internal-only change, especially since we don't
offer any globalfeatures.

However, LND (as of next release) will offer global features, and also
expect option_static_remotekey to be a *global* feature.  So we send
our (merged) feature bitset as both global and local in init, and fold
those bitsets together when we get an init msg.
