nixos/obs-studio: nullable package

Browse Source 
Allows setting `programs.obs-studio.package = null`, which is useful in
case the user wants the appropriate kernel modules from
`programs.obs-studio.enableVirtualCamera`, but does not wish to install
obs system-wide with nixos (e.g., because they want to install it just
for their user with home-manager or maybe via flatpak).
