Print deqp version
deqp starts by printing a line that looks like this:
dEQP Core git-20d674342f008624b82e08f26ed5572c176ba7bd (0x20d67434) starting..
After https://gerrit.khronos.org/c/vk-gl-cts/+/11365, it will look like this:
dEQP Core vulkan-cts-1.3.5.0-163-g20d674342f008624b82e (0x20d67434) starting..
It would be really convenient if deqp-runner could pass this through to its output so that we can verify which version is being run, and remove the hacky workaround in mesa/mesa!21850
