Update pyshark hook to be compatible with versions >=0.5.

Let's put pyshark out of its misery...

[bwoodsend]

Hmm, v0.5.0 fails because pyshark.capture is a namespace package. v0.5.2 puts the __init__.py file back in so we could skip over this one but PyInstaller should be able to handle namespace packages?

[bwoodsend]

Ahh.

Not our bug! ^{Grins smuggly in the knowledge that namespace packages which I've said shouldn't exist have gone and made a mess on someone else}

Yeah, 5.0 has bogus wheels...
