worker: silence type error when calling pickle

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.
