OPTION: map/hlua: make core.set_map() lookup more efficient

0844bed7d3 ("MEDIUM: map/acl: Improve pat_ref_set() efficiency (for
"set-map", "add-acl" action perfs)") improved lookup efficiency for
set-map http action, but the core.set_map() lua method which is built
on the same construct was overlooked. Let's also benefit from this optim
as it easily applies.
