support xattr when extracting packages

Browse source 
This permits storing the result of setcap during package() and applying
the resulting capabilities to the installed program. Formerly, it was
necessary to edit the binary after the fact (and thus dirty the file
according to -Qkk) by using an install scriptlet.

One problem that needs to be solved before this is useful, is preventing
the strip routine from destroying xattrs. This is taken care of in the
previous patch.
