objtool: Fix reloc generation on big endian cross-compiles
Relocations generated in elf_rebuild_rel[a]_reloc_section() are broken
if objtool is built and run on a big endian system.
The following errors pop up during x86 cross-compilation:
x86_64-9.1.0-ld: fs/efivarfs/inode.o: bad reloc symbol index (0x2000000 >= 0x22) for offset 0 in section `.orc_unwind_ip'
x86_64-9.1.0-ld: final link failed: bad value
Convert those functions to use gelf_update_rel[a](), similar to what
elf_write_reloc() does.
