Rollback of https://github.com/androidx/media/commit/f637bb3d40cf37a8ed545e78b45a67bd930e49fd

*** Original commit ***

Remove usage of @ForOverride.

Fixes the gradle compilation failures.

Gradle dependencies need revising if we want to be using this, as
checkerframework is ahead of their latest version, such that we
can't compile.
