L4Sys: fix use of L4SYS_NUMINSTR

Browse Source 
* L4SYS_NUMINSTR counts the instructions that were selected for
  injection and is used by the campaign server to generate experiments
* L4SYS_TOTINSTR counts the total number of instructions executed.
  It is used by the experiment to determine the timeout value.
