CapabilityBoundingSet should not be empty

[fcapano]

Testing on Wayland, on Arch Linux (EndeavourOS) 6.6.15-1-lts.

I've been having a hard time getting the webcam to work. It'd be fine in X11 but now Wayland, where all I'd see is a black screen in Firefox/Chrome/Cheese, and the v4l2-relayd service would crash.

I've narrowed it down to this line in the systemd service definition. Removing it makes it work again:

CapabilityBoundingSet=

Looking at the docs and systemd-analyze capability, I'm not sure which flags would need to be whitelisted, or if the flag is needed at all.

I think a new sed entry in v4l2-relayd/PKGBUILD to remove that line is all that's needed to fix it.
