kernel: Introduce SYS_inject syscall

The SYS_inject syscall will allow the user to inject Kernel Runtime Quantums
(KRQs) into the running kernel. As of now, set paths are not supported and the
initial implementation includes a NULL path used to load all deferrable drivers.

Previously during kernel startup, all deferrable drivers were loaded
automatically. This commit makes it so that they are only loaded when
sys_inject() is called with a NULL path.
