Intentionally exits when propritary GPU drivers are present on system

[madcamel]

Installing proprietary Nvidia or ATI drivers will cause sway to exit
with a warning, requiring additional command-line arguments in order
to operate correctly. The presence of the driver is all that is
required to trigger this behavior. There is no test to check if sway
is actually configured to use the GPU.

The sway development team will not support any configuration involving
proprietary drivers, but I do not believe this is a good reason to
intentionally break people's systems.

This behavior is user-hostile and can cause confusion with users that
have headless GPUs for compute purposes.

The sway development team refuses to discuss this or accept patches,
so I am attempting to work with ubuntu/debian to rectify this issue on
the distribution level.

Patch attached.
