shared: use union instead of _nm_alignas() for static hash-seed

We want the the hash-seed array is alined so it can be used both as
guint, guint32, and guint64 directly. Don't use _nm_alignas() but
instead just add the fields to the union so we get proper alignment.

While at at, also let the seed argument to c_siphash_init() be aligned
to 64 integers. c_siphash_init() does not require that, but it tries to
read the seed as (unaligned) LE 64 bit integers. So, it doesn't hurt.
