Enable masking stop signals within container creation
Expand the use of the Shutdown package such that we now use it to handle signals any time we run Libpod. From there, add code to container creation to use the Inhibit function to prevent a shutdown from occuring during the critical parts of container creation. We also need to turn off signal handling when --sig-proxy is invoked - we don't want to catch the signals ourselves then, but instead to forward them into the container via the existing sig-proxy handler. Fixes #7941 Signed-off-by: Matthew Heon <mheon@redhat.com>
