Lua >= Lua52

See [this](https://github.com/Homebrew/homebrew/pull/29236) PR for more
details. The previous thread for this PR is
[here](https://github.com/Homebrew/homebrew/pull/31996). I was planning
to rebase but I made a fairly awful mistake mid-rebasing and things
went horribly wrong, so here’s to starting fresh and hopefully not
screwing everything up.
Lua >= Lua52

Yup. I figured it out. When I did the rebasing earlier and messed that
up it pulled out the whitespaces in the _END_ patches, and those spaces
were actually there for a reason and without them… No compile. This
should fix it. Both of these compile locally again.
