    SeedEngine: add missing pthread_key_create
    
    libseed has 6 different init functions; some of them are calling
    pthread_key_create() correctly, but some don't. This patch factorizes the call
    to pthread_key_create() so it is correctly called whatever the init function
    used.
    
    The bug was found when testing seed_init_with_context_and_group(). Symptoms:
    when creating a GObject, memory corruption and segfault in
    thread_memory_swap_magazines().
