lstat tests: fix test failure on MSVC

[Bruno Haible]

Similarly, on MSVC, I'm seeing this test failure:

FAIL: test-lstat
================

c:\testdir-posix-msvc\gltests\test-lstat.h:34: assertion 'SAME_INODE (st1, 
st2)' failed
FAIL test-lstat.exe (exit status: 127)

The cause is the same: SAME_INODE always returns false in this configuration.
This patch fixes it.

        lstat tests: Fix test failure on MSVC.
        * tests/test-lstat.h (test_lstat_func): Don't test SAME_INODE values on
        native Windows, unless _GL_WINDOWS_STAT_INODES is defined.
