objtool: Add option to print section addresses
To help prevent objtool users from having to do math to convert function
addresses to section addresses, and to help out with finding data
addresses reported by IBT validation, add an option to print the section
address in addition to the function address.
Normal:
vmlinux.o: warning: objtool: fixup_exception()+0x2d1: unreachable instruction
With '--sec-address':
vmlinux.o: warning: objtool: fixup_exception()+0x2d1 (.text+0x76c51): unreachable instruction
