remove forgotten Nagios files, if any

When we decided to drop Nagios, some files were not removed on the
installations. Since the package does not exist anymore, "pakfire remove
nagios" does not work so we need to clean them up manually in case they
exist.

The third version of this patch makes sure Apache is restarted
afterwards, and includes some forgotten files [sic] as well as it is
now applying for Core Update 121.
