[PATCH xserver] modesetting: use drmmode_bo_import() for rotate_fb

[Olivier Fourdan]

drmmode_shadow_allocate() still uses drmModeAddFB() which may fail if
the format is not as expected, preventing from using a rotated output.

Change it to use the new function drmmode_bo_import() which takes care
of calling the drmModeAddFB2() API.
