Whitelist dmabuf sync ioctl on all linux platforms

This ioctl is used to synchronize zero copy GPU uploads. Non-Chrome OS
builds are starting to be able to use this capability (wayland on linux
desktop, non-CrOS DRM platform builds) so whitelist it more broadly.

Bug:  898234 ,  864914 
Test: chrome --enable-zero-copy --enable-native-gpu-memory-buffers
  on http://media.24ways.org/2009/15/space.html w/ fps counter
