home-cursor: remove IFD when linking icon directories 

An IFD was introduced in bdb5bcad01 from
reading the top-level directories of the `home.pointerCursor.package`
at instantiation time.

This commit removes the IFD introduced when linking icon directories
by linking only the icon directory matching `home.pointerCursor.name`
in `home.pointerCursor.package`. This should be functionally
equivalent to linking all top-level directories of the supplied icon
package as the module only generates cursor configurations pertaining
to the cursor identified by `home.pointerCursor.name`. Deviations in
behavior caused by additional files linked in $HOME/.icons as of the
status quo should be treated as impurities.
