Subject: [PATCH] lua52: Added Lua 5.2 package

Lua 5.2 is required to enable mpv player support of builtin stats OSD.
MPV doesn't support later Lua versions, newer versions aren't backwards
compatible, thus including version in a package name.
Upstream Lua doesn't include pkg-config file, including one from ArchLinux.

See https://github.com/mpv-player/mpv/wiki/FAQ#Why_does_mpv_not_support_Lua_53_or_newer
