edgetpu: Ensure edgetpu and edgetpuvision are built natively

edgtpu and edgetpuvision have a slight quirk in their control files: they depend
on dh-python and python3. Unfortunately, in pbuilder's crossbuild environment,
these packages actually create an unresolvable conflict across architectures and
the package will fail to build.

We can resolve this by using a native build for these packages.
