ci/msys2: re-enable 32-bit builds

The 32-bit builds were disabled, because some packages started
disappearing. MSYS2 is slowly phasing out 32-bit support, but since we
still support it we have to test it somehow. Recent brakage with calling
convention mismatch would be spotted a lot quicker. So enable it, but
with some, not available, packages disabled.
