fix(esx_lib): load imports from the correct resource name

xLib.name was "xLib", which is not a resource, so the import metatable fed it to LoadResourceFile and resolved nothing. It failed silently on Legacy and hard-errored on Enhanced (Resource 'xLib' not found). Point it at the real resource name.
