New ulimit test: bump up minimum nfiles

...and add a comment explaining why. The minimum, determined via
binary search, is actually 27! Anything under that will barf:

   $ bin/podman run --ulimit nofile=26:26 --rm quay.io/libpod/testimage:20221018 true
   Error: OCI runtime error: crun: openat2 `proc/sysrq-trigger`: Too many open files

Play it safe, go with 30.

(Does this seem alarming to anyone else, or am I the only one??)

Fixes: #17860
