[PATCH 01/14] objtool: Fix data alignment in elf_add_data()

[Josh Poimboeuf]

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")
