MINOR: debug: keep runtime limits in postmortem

It's usefull to keep runtime limits (fd and RAM) in postmortem and show them in
debug_parse_cli_show_dev(). Runtime limits are fed in feed_post_mortem_late(),
as we are sure that at this moment that all configuration was parsed and
all applied limits were alredy adjusted.
