[SRU][J][PATCH] UBUNTU: [Packaging] fix typo when calling the old config-check

[Andrea Righi]

BugLink: https://bugs.launchpad.net/bugs/2020413

During the backport of the new annotations model patch set we have
introduced a typo in the execution of the old config-check perl script.

Fix the typo: @perl -> perl.

This bug can be hit only if we are still using the old
configs+annotations model and we opt to not migrate to the new model.
