x11-toolkits/wlroots: backport WLR_DRM_NO_MODIFIERS support

https://github.com/swaywm/wlroots/commit/2bdd1d0896cc broke KMS-based
screen capture e.g.,

  $ sudo LIBVA_DRIVER_NAME=iHD ffmpeg -hide_banner \
      -f kmsgrab -i - \
      -vf hwmap=derive_device=vaapi,scale_vaapi=format=nv12 \
      -c:v h264_vaapi  \
      output.mp4
  [kmsgrab @ 0x81098b000] Using plane 30 to locate framebuffers.
  [kmsgrab @ 0x81098b000] Failed to get framebuffer 131: Invalid argument.
  pipe:: Invalid argument

To make it work again define WLR_DRM_NO_MODIFIERS=1 via environ(7)
before starting a wlroots-based compositor.
