[epiphany/wip/google-safe-browsing: 6/27] gsb-utils: Use GBytes for full hashes too

[Gabriel Ivașcu <gabrielivascu src gnome org>]

commit c822b9788894296c73b721ea3370bcd654e5b5fb

    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().
