[PATCH aiaiai 1/9] aiaiai-email-test-patchset: correct hook calling to actually grab error

[Jacob Keller]

We can't grab the $? value from inside an if block, as the if statement
already changed the return code. Instead, we just call the hook script
without an error section, and then check for errors afterwards. This
corrects an issue where the return code would always be 0, even if the
command failed.
