I have switched neovim package to using LuaJIT instead of the standard Lua for
its speed. Unfortunately, that means we have to have functional lua51 stack in
all distros with this neovim. The only missing package is lua51-bit32, which is
compatibility package providing bitwise manipulation operations for lua 5.1
(they are standard part of 5.2).

I have added lua51-bit32 to openSUSE:Factory
(https://build.opensuse.org/package/show/openSUSE:Factory/lua51-bit32), but I
would like to have it in Leap 42.* and 15.* as well.
