description:
mk/pkgformat: Support INSTALL scripts that rely on UNPACK.

The pkginstall framework had an UNPACK action invoked early
in the PRE-INSTALL stage to unpack scriplets that were invoked
in later stages to perform extra work for installation, removal,
or both.

Add an UNPACK action that is a no-op for any scripts that don't
support the action.
