aiaiai-test-patchset: check for coccinelle scripts first

Rather than always archiving the coccinelle scripts, check to ensure
they exist first. This prevents issues when attempting to build a
non-kernel tree, (ie: ethtool). Will display a warning if coccinelle was
requested but no scripts were found.
