scm: Require CAP_SYS_ADMIN over the current pidns to spoof pids.
Eric fell for my bogus claim that nsproxy->pid_ns was the current' process's pid ns. This isn't true.
Let's fix the bug and rename pid_ns so that no one gets this wrong again.

Andy Lutomirski (2): net: Check the correct namespace when spoofing pid over SCM_RIGHTS Rename nsproxy.pid_ns to nsproxy.pid_ns_for_children
