Explicit dependend on portalocker?

[h-vetinari]

Shouldn't torch/text add an explicit dependency on portalocker now? Without it, I get:

= 979 failed, 204 passed, 12 skipped, 1 deselected, 6 warnings in 495.47s (0:08:15) =

that's >80% failed tests, and probably does not represent a functional torchtext?
