ci: only test against maximum openimageio 2.5.17.0

I'm really having trouble with the changes to make this old
OSL 1.13 work with the brand new OIIO 3.0. For now, rig all the
CI tests to use at most OIIO 2.5.latest.

I'm still contemplating whether the right solution is
(a) do the work necessary to make old 1.13 work with OIIO 3.0+.
(b) just get the beta and release of OSL 1.14 (current main) finished,
    which already works against OIIO 3.0 and which people shold be
    encouraged to change to ASAP.
