fiptool: Factor out setting of image descriptor action 

An image descriptor contains an action and an argument.  The action
indicates the intended operation, as requested by the user.  It can be
pack, unpack or remove.  Factor out setting those fields to a separate
function to minimize code duplication across the various commands that
modify these fields.
