rootless: support a custom arg to the new process
let the process running as euid != 0 pass down an argument to the process running in the user namespace. This will be useful for commands like rm -a that needs to join different namespaces, so that we can re-exec separately for each of them. Signed-off-by: Giuseppe Scrivano <gscrivan@redhat.com>
