re PR fortran/60286 (INQUIRE reports STDOUT as not writable)

        PR fortran/60286
        * libgfortran/io/inquire.c (yes, no): New static const char
        * vars.
        (inquire_via_unit): Use them. Use OPEN mode instead of using
        POSIX's access to query about write=, read= and readwrite=.
