plugingetter: Avoid all caps for constant declarations

Browse source 
Go style calls for mixed caps instead of all caps:
https://golang.org/doc/effective_go.html#mixed-caps

Change LOOKUP, ACQUIRE, and RELEASE to Lookup, Acquire, and Release.

This vendors a fork of libnetwork for now, to deal with a cyclic
dependency issue. The change will be upstream to libnetwork once this is
merged.
