tests: directory seeking is actually prohibited! but the test was wrong

Browse Source 
* path_open of a directory without OFLAGS_DIRECTORY worked on linux,
  but fortunately not on windows!
* the errno is BADF instead of NOTCAPABLE for fd_seek on a directory
* no way for a directory to have the FD_SEEK right.
