Disable blkio.weight test on Ubuntu

Browse Source 
These tests fail with `Error: opening file `io.bfq.weight` for writing:
Permission denied: OCI permission denied`.  Upon examination of the
VMs, it was found the kernel and OS lacks support for the `BFQ`
scheduler (which supplies the `weight` option).  The only available
schedulers are `none` and `mq-deadline`.

Note: Recently updated F32 (prior-fedora) and Ubuntu 20.04
(prior-ubuntu) VMs always use CGroupsV1 with runc.  F33 and
Ubuntu 20.10 were updated to always use CGroupsV2 with crun.
