Kernel+LibC: Use 64 bit values for ino_t

Since the InodeIndex encapsulates a 64 bit value, it is correct to
ensure that the Kernel is exposing the entire value and the LibC is
aware of it.

This commit requires an entire re-compile because it's essentially a
change in the Kernel ABI, together with a corresponding change in LibC.
