setup-hooks/strip.sh: add strip{All,Debug}ListTarget variables

Browse source 
This change mimics existing strip{All,Debug}List variables to
allow special stripping directories just for Target.

The primary use case in mind is gcc where package has to install
both host and target ELFs. They have to be stripped by their own
strip tools accordingly.

Like `stripAllList`, but only applies to packages’ target platform. By default, it’s empty. Useful when supporting cross compilation.
