igt_kms: Dynamically allocate igt_display->pipes

Many GPUs have more then 3 pipes available, so hard limiting this to
I915_MAX_PIPES prevents us from using anything that relies on
igt_display_init() on non-intel systems (since we end up writing out of
bounds and seg faulting). Fix this by dynamically allocating
igt_display->pipes using the number of pipes we've detected on the GPU.
