Cirrus: Add dedicated rootless mode testing

Certain integration tests require execution as a regular user.
This is acomplished by `PodmanTest.PodmanAsUserBase()` wrapping a
specialized execution environment, in `test/utils/utils.go`.  However,
doing this requires passing through python, which vastly increases the
complexity of debugging low-level problems.

This commit introduces a new parallel task, run as a regular user on the
VM as set by three environment variables.  All commands executed in the
``rootless_test.sh`` script, will occur as a real user with a name and
home directory, just as `$DIETY` intended.  All env. vars established
during `environment_setup.sh` (for root) are available.  The PR source
in `$GOSRC` and `$GOPATH` are owned by this user, and ready for use.
