Marc Herbert c6d18ee56b lib/igt_kms.c: remove tests dependency on VT /dev/tty0
Required to run on any recent, freon-based and X11-free ChromeOS release.

v2:
- igt_debug() instead of igt_warn()
- return KD_GRAPHICS instead of -1UL
- print previous mode in debug statements. Among others this help a tiny
  bit with the now confusing debug output ("cannot change" immediately
  followed by a misleading "mode changed").
