[igt-dev] [PATCH i-g-t 18/29] runner: Add support for non-Linux operating systems

[D Scott Phillips]

The runner depends on Linux specific functionality like signalfd
and the watchdog interface. Provide stub functionality for other
platforms so that the runner can continue with reduced
functionality.
