This command allows to pass any binary blob to the kernel as a syspage program. Kernel might be unable to execute it of course, but it will not try to, unless asked to do it (i.e. -x flag is not present for blob in the syspage). Blob can be placed in any memory map, it will be copied by the plo to the destination map, if source != dest. DONE: NIL-571
