First pass at making -F work with --packages*:
* If -F and --packages*
  o We don't need the full build_l, but we do need to call update_pm_nu
    for -a and multiport
  o ... which means we need to export PM_NEEDS_UPDATE unconditionally
  o We want to imply --no-confirm since we're not using the list anyway
  o If not --packages-only lack of a package is a soft fail

While I'm at it, begin making check_fetch_only() useful for --packages*
although we can't do full background fetching for multiple packages yet

Also, revamp the code in check_fetch_only() and where we wait for b/g
distfile fetching to complete to be a lot smarter:
* In check_fetch_only() simplify the code to count fetch processes which
  both makes it faster by avoiding ps, and also makes it smarter because
  it will find fewer false positives.
* In both, poll every 2 seconds, but only output to the console every 6.
  This way we'll be able to exit a lot sooner, but still avoid spamming
  the user with lots of messages.
