objtool: Update sync-check.sh from perf's check-headers.sh

To allow using the -I trick that will be needed for checking the x86
insn decoder files.

Without the specific -I lines we still get the same warnings as before:

$ make -C tools/objtool/ clean ; make -C tools/objtool/
make: Entering directory '/home/acme/git/perf/tools/objtool'
CLEAN objtool
find -name '*.o' -delete -o -name '\.*.cmd' -delete -o -name '\.*.d' -delete
rm -f arch/x86/inat-tables.c fixdep
<SNIP>

LINK objtool

$

The next patch will add the -I lines for those files.
