shell32: SHELL32_GetItemAttributes() 

- correct documentation which incorrectly claimed not to set any
  attribute bits
- retrieve file attributes using SHGetPathFromIDListW() when they are
  not already present in the internal PIDL structures
- add test case to show the previously wrong folder attributes when
  using absolute PIDLs
- fix some memory leaks in the tests
