media-video/obs-studio: migrate to lua-single.eclass

Based on the work of Gergely Nagy <ngg@ngg.hu> from
https://github.com/gentoo/gentoo/pull/18156, however browser source support
has been removed (according to the PR comments chiitoo has not decided yet
which of the competing implementations he prefers) and IUSE=luajit has been
renamed to just "lua" (as done elsewhere, in order to avoid confusion between
luajit and lua_single_target_luajit).

Closes: https://bugs.gentoo.org/752768
Signed-off-by: Marek Szuba <marecki@gentoo.org>
