Draft: ci: compress deqp caselists
What does this MR do and why?
ci: compress deqp caselists
Since deqp-runner 0.20.0 supports compressed caselist, leverage the feature.
The compressed file will be stored in the compressed rootfs,
so from this point of view, it seems useless. Thou, if we account fact
that rootfs gets uncompressed on NFS, now we can transfer smaller file,
while decompression cost almost nothing.
