contrib: Add verify-pacman-repo-db.pl

From the documentation:

verify-pacman-repo-db looks at a pacman repo database and verifies its
content with the actual package files. The database is expected to be in
the same directory as the packages (or symlinks to the packages).

The following properties are verified for each package in the database:

    - existence of the package file
    - file size
    - MD5 and SHA256 checksum (--checksum)
