[Pkg-opencl-devel] Updating beignet backport?

[Rebecca N. Palmer]

jessie-backports currently has beignet 1.0.3, which was recently found 
to cause graphical corruption on some systems 
(https://lists.debian.org/debian-backports/2016/05/msg00114.html).

beignet 1.1.2 (with the patch there to use llvm 3.5) avoids this 
problem, and also adds support for Skylake hardware.

Unfortunately, it also assert-fails (i.e. kills the whole application 
instead of just returning an error) on some invalid OpenCL code; I 
haven't yet had time to investigate this further.
