  Fix key type map entry with unbound vmod not ignored
  
  Currently we only ignore key type map entries with non-zero mods and
  with a zero modifier mask. However, the XKB protocol states ([source]):
  
  > Map entries which specify unbound virtual modifiers are not considered.
  
  So we currently handle `map[Unbound]` key type map entries (all modifiers
  unbound) but not `map[Bound+Unbound]` entries (mix of bound and unbound
  modifiers).
  
  Fixed by properly checking unbound modifiers on each key type map entry.
  
  This also fixes a test that was accidentally passing.
