[ci] Check for usign binary before package index generation #149

Add check for usign binary existence before running make package/index.
If usign is missing from cache, build it using tools/usign/compile.

Also ensures output directory exists before writing checksum file
and uses improved awk filtering for better multi-package support.

Closes #149
