selftests: add pid namespace ENOMEM regression test We recently regressed (cf. [1] and its corresponding fix in [2]) returning ENOMEM when trying to create a process in a pid namespace whose init process/child subreaper has already died. This has caused confusion at least once before that (cf. [3]). Let's add a simple regression test to catch this in the future.
