dpkg: Fix perl modules by moving them to the versioned perl directory

In order for the dpkg perl modules to be used the must reside in the
versioned perl library directory (as to be in the default include path).
Be explicit about this location in our FILES_${PN}-perl directive, so
that if this breaks in the future, the recipe will fail).  We can now
drop the custom do_configure as it wasn't fixing this problem.
