ci: unbreak CI for OIIO auto-build of OCIO for icx case (#1849)

Some explanation is needed: OIIO master recently added the ability to auto-build OCIO when a new enough one is not found at its build time, and bumped the minimum OCIO to 2.2. Sometimes this is triggered by OSL's CI, when OCIO < 2.2, so building OIIO also triggers building of OCIO. All fine, except for the case when we are testing Intel's icx compiler, which OCIO's build system does not recognize and fails to build. So we make a little modification here that lets us, just for that case, ensure that OCIO is pre-built with gcc even though we're building OIIO and OSL with icx.
