cups: new package: Common Unix Printing System

If using systemd, CUPS can be started via socket activation or directly,
in any case it is run as user daemon, group lp. The default spool and
cache locations were moved to /tmp/cups so we don't need to set up a
tmpfs for /var/spool/cups and /var/cache/cups.

sysvinit script is installed from upstream, but untested.

Some config files are only created by cupsd on the first start and not
at install time, so we supply reasonable defaults in projectroot/ in
order to use $(call install_alternative...) on them.
