There were several problems with the systemtap script in pbench:

1) unused variables (script was probably copied from sar)
2) the $script var must have the leading and trailing quotes
   removed.  We embed these quotes for tool options in
   register-tool and start-tools to avoid white-space issues,
   but for some reason the stap command does not like
   dealing with quotes in its arguments (all other tools
   seem unaffected).
3) No required packages were installed (like systemtap!)
4) The directory where systemtap output is collected was
   not created.

Note that while this changeset should apply cleanly without
two other pull requests:
distributed-system-analysis#3
distributed-system-analysis#4
This changeset does require those 2 to function properly
