[PULL 71/85] include/hw/elf: Remove truncating signed casts

[Richard Henderson]

There's nothing about elf that specifically requires signed vs unsigned.
This is very much a target-specific preference.

In the meantime, casting low and high from uint64_t back to Elf_SWord
to uint64_t discards high bits that might have been set by translate_fn.
