euidaccess: Fix test failure on mingw

[Bruno Haible]

On mingw, I'm seeing test-euidaccess failures:

../../gltests/test-access.h:54: assertion 'errno == ENOTDIR' failed
Stack trace:
0xcd2ea6c5 test_access
        ../../gltests/test-access.h:54
0xcd2ea6c5 main
        ../../gltests/test-euidaccess.c:37

        ../../gltests/test-access.h:58

../../gltests/test-access.h:60: assertion 'errno == ENOTDIR' failed
Stack trace:

        ../../gltests/test-access.h:60
0xcd2ea90c main
        ../../gltests/test-euidaccess.c:37
FAIL test-euidaccess.exe (exit status: 1)

Likewise on MSVC.

This patch fixes it.
