Frank Benkstein 6cced78725 FindLua: Fix error when LUA_INCLUDE_PREFIX is set as a variable ...

We use `LUA_INCLUDE_PREFIX` for the result of an internal `find_path`
call and unset the cache entry before each use.  Unset a plain variable
of this name too in case it was set by project code.  Otherwise the
`find_path` call may be skipped and the wrong value used, leading to
errors.
