arm64: Turn u-boot.bin back into an ELF file after relocate-rela
While performing relocations on u-boot.bin should be good enough for booting on real hardware, some simulators insist on booting an ELF file (and yet don't perform ELF relocations), so convert the relocated binary back into an ELF file. This can go away in the future if we change relocate-rela to operate directly on the ELF file, or if and when we stop caring about a simulator with this restriction.
