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

Browse Source 
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

  rm -f arch/x86/inat-tables.c fixdep

  $

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