locking/atomics: Fix out-of-tree build

Building a kernel out of tree with:

  make O=/tmp/b oldconfig
  cd /tmp/b
  make

gives this error:

    CALL    /mnt/kernel/kernel/linux/scripts/atomic/check-atomics.sh
  /bin/bash: scripts/atomic/check-atomics.sh: No such file or directory
  make[3]: *** [/mnt/kernel/kernel/linux/./Kbuild:86: old-atomics] Error 127
  make[3]: *** Waiting for unfinished jobs....

Make the command use the proper build prerequisite which is the absolute
path to the script.
