blob: make opts structures packed

Browse Source 
This ensures that when fields are added, that the
size of the structure will change, ensuring different
versions of the structure can be detected using
sizeof.

Suppress abidiff errors around spdk_bs_opts - structure
size and offsets of all existing members were unchanged,
so there is no ABI breakage here.
