ITL: Add --exclude-process to check_procs 

For check_procs, both the Monitoring Plugins' implementation[0] and the
Nagios Plugin[1] are supporting the "-X" or "--exclude-process" flag to
exclude one or many processes by name. However, this flag is missing
here in the Icinga Template Library.

The Nagios Plugin implementation also comes with "-j" and "-g" for
FreeBSD jails and Linux cgroups, respectively. But, to keep it
compatible, I would ignore these for the moment.

Closes #10226.
