lua: do not use Lua filesystem functions for loading scripts 

Bill Gates did not only create COVID, he's also responsible for the
world's worst OS, where you have to literally jump through hoops of fire
to open files with Unicode file names. Lua did not care to implement any
jumping, so it's our turn to jump.

Untested (on win32).

Fixes: #7701
