sumneko_lua: Use bufdir instead of homedir when resolving root_dir

The problem is that if you open a Lua file outside of a git repository,
it will use your home directory as root directory. This causes Sumneko
to scan your entire home directory for Lua files. Which is bad from both
a security and performance point of view.
