fwget: add -N to only show each package to be installed one by line

[bz]

Summary

pkg-install(8) currently has no option to allow skipping unavail
packages but it will just fail.
We would realy want to try to install as much firmware as found and
possible from the installer.
We work around this by doing one firmware package at a time.
For that it is highly helpful to be able to query (or possibly re-query)
all outstanding fimrware packages in an easily parseable way.

Maybe it would be better to add a -q (quiet mode) as other tools often have ?
so -nq would behave like your -N but we could use -q for other futur things.

What would you do with -q in the non-'-n' case? Also not print the echos in line (old/new) 115/131 and 120/136 or just leave as-is for now?

Yeah I guess so, usually -q doesn't print anything not intended to be a result.

@manu I tried and also switched to getopts.

fwget: add -q for quiet output

Introduce -q to quieten other output (unless -v is also given).

-q together with -n only shows each package to be installed one by line.

While here switch to getopts so -qn works and not just -q -n.

remove "" otherwise multi-pkg show up as one long line

remove quotes

Just leaving this here as this would render some of this logic unneeded (also installer later): https://github.com/freebsd/pkg/issues/2195
