locking/atomics: Check generated headers are up-to-date
Now that all the generated atomic headers are in place, it would be good to ensure that: a) the headers are up-to-date when scripting changes. b) developers don't directly modify the generated headers. To ensure both of these properties, let's add a Kbuild step to check that the generated headers are up-to-date.
