net-irc/weechat: migrate to lua-single.eclass

Both the latest release and the live ebuild.

Upstream build scripts use pkg-config to find Lua so there is no need
to pass Lua version to cmake + it might support LuaJIT. On the other hand,
they only fall back to unversioned module name having enumerated
supported versions so some patching is still necessary.

Both migrated ebuilds build, test and install fine for all supported Lua
implementations.
