  string-desc tests: Avoid test failure on native Windows.
  
  * tests/test-string-desc.c: Include <fcntl.h>, <unistd.h>.
  (main): Expect a file name argument. Write to this file, instead of to
  fd 3.
  * tests/test-string-desc.sh: Pass a file name as argument, instead of
  using '3>'.
  * modules/string-desc-tests (Depends-on): Add close.
