ebtables: Convert to standalone build
* There is no need to create 20 shared libraries on an Android
build. Convert to a standalone build to eliminate this noise.
* Additionally, the scriptage in the Android makefile causes
Ninja to regenerate it's configuration for every build. Fix it.
* These files can be generated by the standard makefile as part
of the "static" target.
