locking/atomic: scripts: factor out order template generation

Browse Source 
Currently gen_proto_order_variants() hard codes the path for the templates used
for order fallbacks. Factor this out into a helper so that it can be reused
elsewhere.

This results in no change to the generated headers, so there should be
no functional change as a result of this patch.
