glob: fix for mingw

[Bruno Haible]

$ ./gnulib-tool --create-testdir --dir=../testdir-glob --single-configure --with-c++-tests glob
produces a testdir that, when compiled on mingw, produces a link error:
undefined reference to `lstat'

This fixes it.

glob: Fix link error on native Windows.
* modules/glob (Depends-on): Add 'lstat'.
