kernel-shark: Xserver, grant access to user root
In order to make connections to the X server, users must be in
the X server allow list. As kernelshark may run with root privileges,
the user "root" must be in this list. There is such logic in
kshark-su-record, but it works only for Wayland X server. Some Linux
distributions use other X servers, so the logic must be executed always.
It grants access to user "root" to initiate connections to the X server from
the local machine.
