dev-games/openscenegraph: migrate to lua-single.eclass

The usual cmake FindPackage(Lua) version hack. Lua compatibility as per
upstream build scripts.

Nb. The unmigrated 3.6.5 ebuild does not set -DOSG_USE_LOCAL_LUA_SOURCE=OFF
in src_configure so it is a) always built with Lua support, and b) linked
against bundled Lua.

Closes: https://bugs.gentoo.org/752573
