Use errorprone.extra_check_modules for error prone checks

Using plugins for error prone checks causes them to be moved from
javac to kotlin, breaking the errorprone javac run which can no longer
find the checks requested in the errorprone javacflags.  Move the
checks to errorprone.extra_check_modules that will always apply to
the errorprone javac run.
