Remove an incorrect @UserIdInt from InputMethodUtils

This is a follow up CL to my previous CL [1], which incorrectly added

  @UserIdInt

annotation to "uid" parameter in

  InputMethodUtils#checkIfPackageBelongsToUid().

As it is a uid not userId, @UserIdInt has never been appropriate for
that parameter.

This CL must have no observable behavior change since @UserIdInt
doesn't change any runtime behavior.
