automake: don't forget to pick wglext.h in the tarball

Earlier commit reworked the header install rules, to ensure that the
correct ones are installed only as needed.

By doing so it dropped a wildcard which was effectively including the
wglext.h header in the tarball.

Add the header to the top-level noinst_HEADERS, since the it is not
meant to be installed (autoconf is not used on Windows plaforms).
