channeldb: embed the instance of boltb within DB struct

Browse Source 
This commit modifies the composition of the boltdb pointer within the
DB struct to use embedding.

The rationale for this change is that the daemon may soon store some
semi-transient items within the database which requires us to expose
the boltdb’s transaction API. The logic for serialization of this data
will likely lie outside of the channeldb package as the items that may
be stored in the future will be specific to the current sub-systems
within the daemon and not generic channel related data.
