rm operation can fail

[berland]

This seemingly safe operation

komodo/komodo/cli.py

Line 137 in 315fab7

shell(f"rm -rf {args.prefix}/{args.release}.delete", sudo=args.sudo)

can actually fail, if for example there are NFS lock files present in the directories. This happened in
https://github.com/equinor/komodo-releases/actions/runs/4309163140/jobs/7516226400
(for an unknown reason).

When komodo building crashes like this for bleeding, it leaves bleeding in a broken state (it has already been moved to its final destination, but it has at least not fixed the shebangs and not done the pip installs).

This is not a problem anymore, as we have timestamped bleeding builds.
