Cirrus: Bump Fedora to release 35 & Ubuntu to 21.10

The Fedora 35 cloud images have switched to UEFI boot with a GPT
partition. Formerly, all Fedora images included support for runtime
re-partitioning. However, the requirement to test alternate storage
has since been dropped/removed.  Rather than maintain a disused
feature, and supporting scripts, these Fedora VM images have reverted
to the default: Automatically resize to 100% on boot.
