container: Allow 'container-excursion' to the same namespaces.
Before that, 'container-excursion' would call 'setns' even when the target namespace is the one the caller is already in, which would fail. * gnu/build/linux-container.scm (container-excursion): Introduce 'source' and 'target'. Compare the result of 'readlink' on these instead of comparing file descriptors to decide whether to call 'setns'. * tests/containers.scm ("container-excursion, same namespace"): New test.
