Cirrus: Add e2e task w/ upstream netavark

This PR adds the CI mechanisms to obtain the latest upstream netavark
binary, and set a magic env-var to indicate e2e tests should execute
podman with `--network-driver=netavark`.  A future commit implement
this functionality within the e2e tests.

Due to the way the new environment is enabled, the standard task name
is too long for github to display without adding ellipsis.  Force the
custom task name `Netavark Integration` to workaround this.  At some
future point, when netavark is more mainstream/widely supported, this
custom task and upstream binary install can simply be removed - i.e.
netavark will simply be used by default in the normal e2e tasks.
