Add support for preopt with uses-libraries
Required libraries are specified with LOCAL_USES_LIBRARIES
Optional libraries are specified with LOCAL_OPTIONAL_USES_LIBRARIES
The make rule cross references the libraries against what's stored
in the manifest.
Verification is enabled if LOCAL_ENFORCE_USES_LIBRARIES is true. This
defaults to true if either of LOCAL_USES_LIBRARIES or
LOCAL_OPTIONAL_USES_LIBRARIES are specified.
