bitbake: toaster: remove cut and paste cruft

There was a superfluous section in toaster start/stop script that was
setting the TOASTER_DIR and had a set of comments around that setting.
This was done in two places and only the last one was effective. This
patch removes the spurious section to make it clearer what was
happening and what TOASTER_DIR was actually getting set to.
