[PATCH igt] tests: Use igt_device_set_master

[Chris Wilson <chris@chris-wilson.co.uk>]

A few tests only require DRM_MASTER privileges for a subset of gen or
tests, and so open the device as normal and conditionally call
drmSetMaster. Translate these over to using igt_device_set_master(),
which includes a bit more debugging for when it fails.
