contrib: relpath.sh /lib /include [PR119081]

Browse Source 
Previously, if the common ancestor of the two paths is / we would print the
absolute second argument, but this PR asks for a relative path in that case
as well, which makes sense for the libstdc++.modules.json use case.

	PR libstdc++/119081

contrib/ChangeLog:

	* relpath.sh: Give relative path even at /.
