[PATCH] ids-functions.pl: Skip deleted.rules files

[Stefan Schantl <stefan.schantl@ipfire.org>]

[-- Attachment #1: Type: text/plain, Size: 1065 bytes --]

These rulefiles are used by various providers as a kind of reference and
to store rules which have been taken out for correctness, performance
reasons or because of other reasons.

Fixes #12794.
