Use ioctl(FIONREAD) rather than recv(MSG_PEEK) to implement Socket.available.

As well as avoiding unnecessary work, this also means we can reuse the native
code we already have for ioctl(FIONREAD), though we need to change the
interface to take FileDescriptor rather than int, and extract the int on the
native side.
