media-gfx/imv: add 4.3.1_p20211221

Mostly to include libgrapheme support for those that don't want
to pull icu on minimal systems (with a minimal image viewer).
Uptream had no activity since 2021, so not expecting a release soon.

Also add workaround to display animated gifs even if USE=freeimage
is set (which prevented using libnsgif with animation support).

+Upstream priorizes freeimage in general, but nsgif supports animated
+gif while freeimage displays them as a static image. This allows setting
+USE=freeimage while still getting animations if (optional) USE=gif.
