init-radosgw: run RGW as root

The ceph-radosgw service fails to start if the httpd package is not
installed. This is because the init.d file attempts to start the RGW
process with the "apache" UID. If a user is running civetweb, there is
no reason for the httpd or apache2 package to be present on the system.

Switch the init scripts to use "root" as is done on Ubuntu.
