[epiphany/wip/google-safe-browsing: 2/7] gsb-utils: Use GBytes for full hashes too

[Gabriel Ivașcu <gabrielivascu src gnome org>]

commit c73b38159637aba70b225bfe169c4b58bf40b1d2

    gsb-utils: Use GBytes for full hashes too
    
    This allows better handling in g_hash_table_new_full() and
    g_list_copy_deep() due to g_bytes_hash(), g_bytes_equal(),
    g_bytes_ref(), g_bytes_unref().
