fix reading problem on 64-bit machines in QProcess and socket engine

QProcessPrivate and QNativeSocketEnginePrivate were reporting a wrong
number of bytes available on 64-bit machines, due to use of size_t in
ioctl. That was required by Irix, which we dropped support for, so we
can also drop size_t
