fix(lua): restore priority of the preloader

lewis6991 · lewis6991 · commit b518b577ea89 · 2022-02-05T21:46:04.000Z
Neovim currently places its own loader for searching runtime files at
the front of `package.loaders`. This prevents any preloaders in
`package.preload` from being used. This change fixes that by moving the
default package preloader to run before Neovim's loader. For example,
LuaJIT provides preloaders for the built-in modules `ffi` and `bit`, so
this optimisation will improve the loading of those.
