Remove $stow_path parameter from unstow_{contents,node}{,_orig}()

Browse source 
Unlike with the stow_{contents,node}{,_orig}() counterpart functions,
when unstowing, it's not necessary to pass the $stow_path parameter
because it can never differ from $self->{stow_path}.

The stow_*() functions need this for the corner case of unfolding a
tree which is stowed from a different stow directory to the one being
used for the current stowing operation (see the "Multiple Stow
Directories" section of the manual).
