objtool: Fix data alignment in elf_add_data()
Any data added to a section needs to be aligned in accordance with the
section's sh_addralign value. Particularly strings added to a .str1.8
section. Otherwise you may get some funky strings.
Fixes: dd590d4d57eb ("objtool/klp: Introduce klp diff subcommand for diffing object files")
