Remove (binary) casts from phar stub

[kelunik]

Even if #2187 doesn't get merged (now), there's no reason to use (binary) as PHP 6 forward compatibility is not a concern anymore.

Closing, there's a separate commit in the mentioned PR that is complete: 33dbcea

I think this should be merged as it does not break anything, and it does ease up forward compatibility in whatever direction we take PHP

ccing @dshafik and @krakjoe as this should go into 7.1 if the time allows us, if not then master is sufficient

@kelunik can we have this branch back please ?

I'm happy to merge this one change, it is all that is required to ease forward compat ... we don't need all those test changes to achieve the same thing, I'm more reluctant to commit those.

@krakjoe: We need to adjust the tests that check for the length, too. See the linked commit, I think you can just cherry pick that one.

Oh I see, got it.
