[PATCH 3/9] bitbake: toaster: allow TOASTER_DIR to be overridden from cmdline

[David Reyna <david.reyna@windriver.com>]

From: Awais Belal <awais_belal@mentor.com>

TOASTER_DIR is used for higher level toaster artifacts
such the SQL DB and creating toaster internal build
directories for projects. Prior to this change it was
evaluated as `dirname $BUILDDIR` and user had no control
over it. This change allows to override this variable
from the command line for more flexibility. The variable
defaults to its original setting if the optional argument
is not passed.
