Make KTR_SYSRET records variables variables sized, leaving out the

retval on error, including a long long retval on successful lseek(),
and including a register_t retval for other successes.  This fixes
lseek reporting on ILP32 archs.

While here, reworking internal kern_ktrace.c bits to be able to pass
two buffers to ktrwriteraw(), so we can avoid mallocing a buffer
in some cases and so that KTR_GENIO logs are split at PAGE_SIZE,
not PAGE_SIZE-sizeof(struct ktrgenio)
