  acl, file-has-acl tests: Strengthen tests on Cygwin.
  
  Suggested by Corinna Vinschen in
  <https://lists.gnu.org/archive/html/bug-gnulib/2025-03/msg00126.html>.
  
  * tests/test-set-mode-acl.sh: On Cygwin, use group 1 instead of the
  non-existent group 0.
  * tests/test-copy-acl.sh: Likewise.
  * tests/test-file-has-acl.sh: Likewise.
