Since bumping luv from version 1.9.1 to 1.22.0, building luvi fails, as
"luv.h" now includes "compat-5.3.h", which is locally shipped as a
dependency to lua-compat-5.3.
Fixing the issue reveals, that luvi is using `luaL_newlib` which is not
available in the Lua 5.1 API. Building luvi with luv 1.9.1 was not an
issue before, because luv 1.9.1 defined `luaL_newlib` in luv.h, which
was removed in 1.22.0 in favour of using lua-compat-5.3.
Therefore, add a patch which defines `luaL_newlib` in luvi.h.
