drm: drop DRM_AUTH requirement from AUTH_MAGIC ioctl
Currently only an authenticated master can authenticate another client.
In practise the client can only be master if CAP_SYS_ADMIN is present,
although having the CAP also sets the client as authenticated.
Thus DRM_AUTH in AUTH_MAGIC's "DRM_AUTH | DRM_MASTER" is superfluous.
Notices while working on IGT tests.
