ci/deqp: really remove the uncompressed results.csv file

Arguments are parsed in order, so the `-c` here causes that first `--rm`
won't get applied and then it gets overriden by `-o` which writes the file.

Sadly zstd won't report this as a issue, but that's being reported in [1],
so maybe in future versions zstd will warn about it.
