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.
