Remove unneeded DKMS dependencies from qubes-video-companion

[tlaurion]

How to file a helpful issue

The problem you're addressing (if any)

Only tested on debian-12, but the package depends on other packages to DKMS v4l2loopback.ko kernel module already shipped by default?

The solution you'd like

Not deploy unneeded DKMS dependencies since qubes-video-companion is not contrib package but part of qubesos repos, and therefore, needed kernel module v4l2loopback.ko is already packed deployed and installed.

The value to a user, and who that user might be

Not loose time after each template kernel update to run dkms for nothing:

user@localhost:~$ sudo apt install qubes-video-companion

That dkms is needed if you use in-qube kernel, instead of dom0-provided one. Unfortunately, it isn't possible to set package dependencies related to which kernel is running (but even then, it probably won't be enough, as template may use different kernel than qubes based on it).

[marmarek]

Maybe a better approach would be to drop the dependency, but document that if one wants to use in-qube kernel, then extra package (v4l2loopback-dkms) is needed?

[tlaurion]

@marmarek as you see fit!
