channeldb: modify the NumUpdates field in ChannelDelta to be a uint64

Browse source 
This commit modifies the running update count within all ChannelDelta’s
to track the number of updates using a uint64 rather than a uint32.
This change reflects the fact that the obsfucated commitment hints are
to be encoded using a 48-bit integer, rather than a 32-bit integer.
