Tools: Manage obsolete files in /usr/local/bin

/usr/local/bin had some obsolete versions of scripts that since then
have been moved to /usr/bin.  To properly manage those, we add
symbolic links pointing to /usr/bin.  Also, the requirement of the
jobutils package is moved from toollabs::bastion and
toollabs::webserver to gridengine::submit_host.  This fixes bug
