ids-functions.pl: Do not longer extract all rulefiles in archive.

Only extract rulefiles which are located in a rules directory and/or in the archive
root.

This prevents us from extracting experimental or binary rules etc. which
often are located in corresponding sub-directories.

Reference: #12794.
