Subject: [PATCH] create-diff-object: Fix out-of-range relocation error message
Showing sec+addend isn't valid, show sym+addend instead.
Before:
create-diff-object: ERROR: sys.o: kpatch_check_relocations: 2550: out-of-range relocation .rodata.__kpatch_do_sys_uname.str1.1+139 in .rela.text.__kpatch_do_sys_uname
After:
create-diff-object: ERROR: sys.o: kpatch_check_relocations: 2550: out-of-range relocation .LC7+139 in .rela.text.__kpatch_do_sys_uname

Subject: [PATCH] create-diff-object: Fix out-of-range relocation check
Improve the relocation check for the case where the referenced symbol
isn't at the beginning of the section.
Note that the check still isn't perfect, as many relocations have a
negative addend. But it's still a lot better than nothing.
