objtool: Fix seg fault with clang-compiled objects
commit ce90aaf5cde4ce057b297bb6c955caf16ef00ee6 upstream.
Fix a seg fault which happens when an input file provided to 'objtool
orc generate' doesn't have a '.shstrtab' section (for instance, object
files produced by clang don't have this section).
