MFC: VOP_LISTEXTATTR.9, 1.7
MFC: VOP_LISTEXTATTR.9, 1.7

  Update man page to reflect the fact that VOP_LISTEXTATTR
  does not return a list of ASCII NUL terminated strings.
  Instead, a list of attribute names is returned, where each
  list entry consists of one byte for the name length, followed
  by the name, without a terminating ASCII NUL.
  This in similar to change 1.17 to extattr_get_file.2
