tests: firmware_update: Clean up some use of reinterpret_cast<>()

I'm reworking the QueryDownstreamIdentifiers tests, so let's get them
into reasonable shape before further modifications.

The primary change is replacing open-coded buffer sizing, allocation,
and type-casting with use of PLDM_MSG_DEFINE_P(), which gives us a
pointer to an appropriately-aligned stack-allocated instance of `struct
pldm_msg` with appropriate space in the object for the payload flexible
array.
