Joachim Nilsson 6f61e8e915 Remove hard-coded paths to system tools available in $PATH
Since at least a44daf2 both run() and run_interactive() can access all
system tools in _PATH_STDPATH.  A system that uses non-standard paths,
e.g. /system/bin and /apps/bin, should update _PATH_STDPATH.

For reference, see issue #69 and PRs #70 and #72.
