[gtksourceview/wip/chergert/snippets] fix const'ness of search-path usage in various managers

[Christian Hergert <chergert src gnome org>]

commit 42c425bcce9f9c25ebc4e8b2e09a2ca312f01c66
Author: Christian Hergert <chergert redhat com>

    fix const'ness of search-path usage in various managers
    
    These should be "const gchar * const *" since we're breakin API/ABI
    anyway. This is not an ABI break, but it will cause warnings in existing
    code that was passing "gchar**". This is more correct however since we
    do not take any references or mutate the strings, or pointer to strings.
