media-libs/vigra: fix OpenEXR-3 dependency

Without the patch, OpenEXR-3 support is not included, regardless of USE=openexr

(...)
-- Searching for OpenEXR
--    in default locations
-- Could NOT find OpenEXR (missing: OPENEXR_HALF_LIBRARY OPENEXR_ILMIMF_LIBRARY)
(...)

With it, hugin-2021.0.0 (correctly) detects OpenEXR-3 support in vigra,
and compiles just fine, closing below bug.

(Upstream patch was modified scrubbed)
