[Piglit] [PATCH 1/1] cmake: bump gbm dependency to 17.1

[Jan Vesely]

c6e1dc5247 switched to use gbm_bo_get_offset and gbm_bo_get_stride_for_plane.
These symbols were added in mesa 17.1. Since there is no alternative to using them, bump the gbm requirement to 17.1.

Fixes: c6e1dc5247 "piglit_drm_dma_buf: fix GPU offsets and strides"
