rHGa0674e916fb6: worker: silence type error when calling pickle
Summary

pytype is complaining that the argument to pickle.load() is not an
IO. pytype isn't wrong: _blockingreader doesn't implement
io.RawIOBase, only read() and readline(). But it appears this is
enough for pickle. So we silence the false positive.

This fixes a regression introduced by D12304 /
cc0e059d2af8: worker: remove Python 2 support code.
