libdtrace: Add kinst support
kinst does not instantiate its probes automatically, it only does so on
demand via an ioctl interface implemented by /dev/kinst. This change
modifies libdtrace to perform that work when the script references the
kinst provider, similar to the way pid provider probes are implemented.
