toaster: cleanup of bin/toaster startup code

This cleanup fixes a few issues:

    1) Removes the superflous code to set toasterconf.json
       - this isn't used and referenced meta-yocto
    2) Changes exit to return so we don't surprise the user by exiting their shell
       - this is necessary because it is being sourced
    3) Removes the last references to the old TOASTER_MANAGED variable
       - this is historical and no longer used.
    4) Adds -t parameter to lsof
      - This stops it from dying on odd filesystems and is much
        faster since all we are using are processes anyway
    5) Handles start and stop as params
      - it was easy to confuse the script especially
        if we were calling it with parameters.
      - if start/stop isn't specified, it will still toggle
