st/pbo: fix pbo uploads without PIPE_CAP_TGSI_VS_LAYER_VIEWPORT and skip gs

the previous commit handling this forced geometry shader usage for all cases,
but this is not ideal, so instead there are now fragment shader variants for
both depth==1 and depth!=1, corresponding to the existence of gl_Layer in the
shader

virgl: fix BGRA emulation artifacts during window resize

On some devices, window resizing results in flashes of blue- and

finished.

This fix ensures that the emubgra tweak used for GLES virgl hosts

Additionally, I added a subcommend to turn the .csv into a junit output
that we can expose to gitlab.  Now, the pipeline's status page will report
the failed testcases, and the "detail" button will give you a link to the
.XML to view for the failure.  (We don't report all testcases because it's
too much load for the gitlab server).  Note that this will 404 for the
LAVA runners for now, as they don't retain artifacts in gitlab (the plan
is to eventually have them minio upload the artifacts).

This uprev also includes a deqp output parsing fix, resulting in us
catching a couple more failures in some drivers.
