Update license definitions under art/

All the GPL code under art/ is in art/dt_fd_forward, art/openjdkjvm
or art/openjdkvmti, which have their own license files, so remove
GPL from the top level licenses.

The modules in Android.mk are phony modules with no code of their
own, so set the licenses to Apache 2.0.

All the files in art/dt_fd_forward, art/openjdkjvm and art/openjdkvmti
are annotated with the classpath exception, so remove GPL from their
license list, leaving GPL with classpath exception.

Test: none
