ci: optimize openexr build time, don't run nightly on forks (#2097)

* When building openexr as a dependency for OSL, there is no need
  to build the openexr command line utilities, saving a bit of build
  time.

* Fix an error from PR #2074 where we tried to disable nightly CI runs
  on forks -- we didn't make the right change to the Windows jobs, so
  they were still running.
