gsocket: Use gsize to track native sockaddr’s size

Browse Source 
Don’t use an `int`, that’s potentially too small. In practical terms,
this is not a problem, since no socket address is going to be that big.

By making these changes we can use `g_memdup2()` without warnings,
though. Fewer warnings is good.
