WITH_GETLINE patch from FreeBSD ports x11-drivers/xf86-video-intel

Patch for --enable-debug from DragonFly dports
x11-drivers/xf86-video-intel29 

Additional patch for DragonFly because struct drm_i915_gem_mmap
has a field flags.

https://bz-attachments.freebsd.org/attachment.cgi?id=20233

Fix SNA for drm-v4.11 or later by disabling I915_USERPTR_UNSYNCHRONIZED

I915_USERPTR_UNSYNCHRONIZED is broken since drm-v4.11
