Add PermissionManager enforcement support to RequiresPermissionDetector

The `RequiresPermissionDetector` did not recognize permission enforcement
checks performed using `android.permission.PermissionManager`. This
caused the lint check to incorrectly flag methods as having "too broad" a
`@RequiresPermission` annotation, even when the permission was correctly
enforced at runtime.
