meta: Merge rar container with wine

I'll rename this later, but basically I got tired of the vastly
increased build times due to having multiple containers, and would
rather combine containers where possible.

Although unfortunate, this should still be better than not using
containers at all, and by making the usage of such containers easier,
the probability of using them increases as well.
