Ben Wolsieffer 025b08b580 protobuf3_21: don't build tests on 32-bit platforms
The tests fail to build on 32-bit platforms, due to an upstream bug which will
be fixed in 3.22. Previously, this was holding back the default protobuf version
on 32-bit platforms to 3.20, which in turn broke packages such as mypy-protobuf
which require 3.21

This commit disables building the tests on 32-bit platforms, allowing 3.21 to
build. Note that we don't ever run the tests on any platform, but they are
normally still built.

Now that 3.21 builds on 32-bit, this commit also unpins 3.20 as the default
version.
