app-emulation/dxvk: fix setup script with wine[wow64]

Currently it will try to install both 32bit and 64bit dlls
in system32. Very few likely use wow64 so far, but this could
come biting later without a revbump.

Ideally do not want to use these scripts anymore and write
something new that could be packaged separately and shared
between dxvk, vkd3d-proton, and potential new packages.
Albeit haven't explored the cleanest way to do this yet,
so just do a dirty sanity check + fallback for now (wish
could just use these directly from system paths, but wine
really does not seem to offer a way to do this).
