MFH: r454266 r454332

Fix [DE]SELECTED_OPTIONS to lazily evaluate as late as possible.

If a port modifies OPTIONS_UNSET after including bsd.port.options.mk
then these values were wrong even though all of 'showconfig',
'pretty-print-config', and the package generated all had the expected
options.

Only Poudriere and synth use these variables for incremental build checks.

Follow-up r454266: Sort and remove duplicates for [DE]SELECTED_OPTIONS.

Some ports like graphics/povray-meta do funky things like add the same
option into PORT_OPTIONS twice.  This also avoids a new leading blank
space in some cases.
