ci: Remove Piglit replayer from test-vk container/rootfs

We've been building the Piglit replayer in the test-vk container/rootfs,
but all trace-replay testing in CI is actually done using the test-gl
rootfs.

Despite the naming, the "gl" and "vk" rootfs variants don't correspond to
the graphics API being tested - just the different sets of tools
bundled.
The required tools for trace replay are already included in the test-gl
rootfs, so there's no need to build or use the test-vk variant for this
purpose.
