Fix 'exclude_tree' in wp_list_categories().

Browse Source 
The 'exclude_tree' parameter must be compatible with 'hierarchical';
previously, 'hierarchical' canceled it out. This changeset also makes it so
that 'exclude_tree' is compatible with 'exclude'. When both are passed, and
'hierarchical' is true, the descendant trees of terms in both parameters will
be excluded from matched terms.

Props tott, webord, MikeHansenMe.
Fixes #12981.
