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.
