Always report ENOSYS in init

While rare, encountering an unimplemented system call early in init is
catastrophic and difficult to debug.  Even after a SIGSYS handler is
registered, such configurations are problematic.  As such, always report
such events for pid 1 (following kern.lognosys if non-zero).
