locking/atomic: scripts: build raw_atomic_long*() directly

Browse Source 
Now that arch_atomic*() usage is limited to the atomic headers, we no
longer have any users of arch_atomic_long_*(), and can generate
raw_atomic_long_*() directly.

Generate the raw_atomic_long_*() ops directly.

There should be no functional change as a result of this patch.
