Open a terminal type vulkan-smoketest instead of a glxgears type window it will
segfault.

What should happen is a glxgears like window will open and render properly
instead of segfaulting.
It appears that the culprit is an old or broken libvulkan_radeon.so provided by
mesa-vulkan-drivers.
As a test I renamed the old lib and dropped in a newer version from
oibaf's ppa. smoketest now passes steam's The Talos Princible and Mad
Max now work properly in Vulkan mode as well instead of segfaulting.
This issue is also present on Zesty and fixed in both Oibaf's and
Padoka's ppa's since April back when they were rolling 17.2 mesa.
I have no idea if libvulkan_intel.so also needs updating no hardware to
check.
