podman image tree: restore previous behavior

Browse Source 
The initial version of libimage changed the order of layers which has
now been restored to remain backwards compatible.

Further changes:

 * Fix a bug in the journald logging which requires to strip trailing
   new lines from the message.  The system tests did not pass due to
   empty new lines.  Triggered by changing the default logger to
   journald in containers/common.

 * Fix another bug in the journald logging which embedded the container
   ID inside the message rather than the specifid field.  That surfaced
   in a preceeding whitespace of each log line which broke the system
   tests.

 * Alter the system tests to make sure that the k8s-file and the
   journald logging drivers are executed.

 * A number of e2e tests have been changed to force the k8s-file driver
   to make them pass when running inside a root container.

 * Increase the timeout in a kill test which seems to take longer now.
   Reasons are unknown.  Tests passed earlier and no signal-related
   changes happend.  It may be CI VM flake since some system tests but
   other flaked.
