Don't advertise rotation support without hardware acceleration v2
Rotation currently doesn't work without acceleration (doesn't actually
rotate with Option "NoAccel", crashes with Option "AccelMethod" "none"
or when glamor fails to initialize) and would probably be too slow
anyway.
v2: Also remove now dead code checking for ShadowFB from
drmmode_crtc_scanout_allocate().
