Remove tests requiring Python 2 support.
This is in preparation for disabling Python 2 functionality. There is more code
and tests related to Python 2 support, but these are the ones that fail when
`--incompatible_python_disable_py2=true`.
This also revealed that rejecting Python 2 settings for `py_runtime` and
`py_runtime_pair` will have to wait until after the flag flip. This is because
the auto-detecting toolchains define some py2 toolchains, so in order to make
tests pass, those have to be removed, but doing so would break Python 2 support
prior to the flag flip. The other rules still reject them, though, which is
plenty sufficient.
