(configd) configd actions missed second level actions, output is fine now but nesting actions may need some more thinking

o Retain the timeout priorities while cutting the timeouts to
  10% of what they were before (30s).
o Metadata is always flused by default, but change timeout to
  match the others anyway.
o Reorder the sysctl list for convenience white at it.

The current fix now works as expected and always brings back the
console login after an unclean shutdown, which was previously not
happening.  A small quirk, however, is that while the base system
recovers, the OPNsense backend on top may not fully recover directly
after the unclean shutdown.  In those instances, a manual reboot
will bring back the fully operational system and its services.

The unclean shutdown dilemma is, however, an unavoidable occurrence
and any kernel panic or power failure can corrupt the file system
into an unrecoverable state.  Having snapshots or backups at hand is
a good habit to get into, which can also 'fix' the eventual breakdown
of a physical disk.

o pwd_mkdb(8)'s `-p' likely only cares about /etc/passwd
o Regenerate for each phase, pkg(8) seems to like that
o Also restore a clobbered /etc/shells including our root shell

runtime regeneration.  Not pretty, but better than triggering it
only once on bootup.  More clog -> newsyslog migration to be done
soon.
