Sets the list of directories where the lm looks for
language files.
If dirs is NULL, the search path is reset to default.
Note
At the moment this function can be called only before the
language files are loaded for the first time. In practice
to set a custom search path for a GtkSourceLanguageManager,
you have to call this function right after creating it.
