patch 9.2.0294: if_lua: lua interface does not work with lua 5.5
Problem: if_lua: lua interface does not work with lua 5.5
(Lyderic Landry)
Solution: Use the new lua API `luaL_openselectedlibs()`
(Yee Cheng Chin)
Lua 5.5 removed the API function `openlibs` with `openselectedlibs`,
with `luaL_openlibs` replaced by a macro that just calls the new
`luaL_openselectedlibs` in the headers (see lua/lua@d738c8d18). This
broke Vim's dynamic Lua build as we try to redefine `luaL_openlibs`
ourselves and also this function can no longer be loaded from the lib.
Update the code to use the new API call instead to fix the issue.
