[OE-core] [PATCH V2] musicbrainz: handle rebuilds

[Ross Burton]

When rebuilding build-native already exists.  Sadly handling the directory
existing causes cmake to forkbomb when rebuilding, so delete an existing
build-native.

Also remove a variable that cmake warns isn't being used, and just build the
tool that we need natively, not the entire library.
