            Fix conflict with kmscon

On Fedora 45 Beta, kmscon takes the GPU before cosmic-greeter, so the
users are stuck on the console.
This will prevent kmscon to run on the same VT as cosmic-greeter.

+Subject: [PATCH] feat: systemd service, conflicts with kmscon
+
+kmscon is replacing agetty/fbcon on Fedora, and thus the systemd service
+should conflict with kmsconvt@tty1 instead of agetty@tty1
+
+Otherwise both kmscon and cosmic greeter compete for the graphic cards.
