Buildah run was exiting with the correct exit code, when a container
failed. Buildah bud was not, so this should fix this.
Also switched to the proper exit codes when containers fail. When
Buildah fails to execute it will exit with a 125 exit code like
Podman does. If a command fails to execute inside of a container
we will exit with a 126. Currently we do not support the 127 for
exiting when the command does not exist.
