[INSTRM-999] get actor product dir from eups

from Actor.Actor._init_

        # This requires that the actor be started from its root directory. Not great,
        # but it removed dependance on another environment variable. Could import eups and
        # ask that object.
        self.product_dir = os.getcwd()

product_dir is now determined using current directory.
eups is now used to get version, hence there is no good reason to avoid using environment variable.
