cockpit: Add runtime dependency on GNU Coreutils

The BusyBox version of mv does not have the -Z flag for setting SELinux
security context. This results in failure
when the cockpit-certificate-helper script is executed.

Depend the package on GNU Coreutils to make sure that the proper version
of mv is installed.
