Subject: [PATCH] media-libs/ctl: restrict dependency on media-libs/openexr

Package currently doesn't build with OpenEXR-3/Imath. This revision adds
an upstream patch to disable certain tests if no OpenEXR-2 is available
and thus needs to depend on IlmBase only.

Bug: https://github.com/ampas/CTL/issues/100
Closes: https://bugs.gentoo.org/878247
