From: Daniel Stone <daniels@xxxxxxxxxxxxx>
Mirroring addfb2, add tests for the new ioctl which will return us
information about framebuffers containing multiple buffers, as well as
modifiers.
Changes since v3:
- Add subtests to ensure handles aren't returned for non-root and
non-master callers
- Fix getfb2-handle-not-fb to use getfb2
Changes since v1:
- Add test that uses getfb2 output to call addfb2 as suggested by Ville
