It is not possible to run host system executables like modinfo, pkexec, and modprobe inside a Flatpak sandbox. However, Flatpak provides a way to run command on the host system: the flatpak-spawn executable. flatpak-spawn is a tiny helper that, when executed with the '--host' parameter, talks to the org.freedesktop.Flatpak D-Bus interface to run and retrieve the return value of the executable. This provides OBS Studio a way to escape this sandbox limitation without opening large holes in the sandbox. Make v4l2's implementation of VirtualCam run system commands using flatpak-spawn when inside a Flatpak sandbox. The detection of the sandbox is done by checking the existence of the /.flatpak-info file, which is created by Flatpak itself, and only exists inside the sandbox. If OBS Studio is not running inside a Flatpak sandbox, run the exact same command it used to run before this commit. Add the permission to talk to the org.freedesktop.Flatpak D-Bus interface to the Flatpak manifest, so we can run flatpak-spawn with the '--host' parameter. Notice that the same constraints apply with and without Flatpak: the host system needs to have the v4l2loopback kernel module available for the v4l2 implementation of VirtualCam to work.
