Rename AndroidFrameworkLintChecker's package to com.google.android.lint

The previous package name com.android.lint is not allowed for custom
lint checks because lint thinks any package with com.android. is its own
API, so it performs a reflection check to see if it is a known API, but
it fails because it is a custom check.

For testing, verify that the lint report does not report an Obsolete
Custom Lint Check issue.
