remove problematic corosync-qdevice.init

remove problematic corosync-qdevice.init

without this we seemingly cannot install corosync-qdevice on PVE 5.0
While the programm and its systemd service file get installed
correctly the package configuration fails with:

----
Setting up corosync-qdevice (2.4.2-pve2) ...
insserv: Service corosync has to be enabled to start service corosync-qdevice
insserv: exiting now!
update-rc.d: error: insserv rejected the script header
dpkg: error processing package corosync-qdevice (--configure):
subprocess installed post-installation script returned error exit status 1
----

This error gets printed while corosync is enabled and started without
failure. So just remove the problematic file.
