Subject: locking/atomics: Change 'fold' to 'grep'

Some distibutions and build systems doesn't include 'fold' from
coreutils default.

.../scripts/atomic/atomic-tbl.sh: line 183: fold: command not found

Rework to use 'grep' instead of 'fold' to use a dependency that is
already used a lot in the kernel.

[Mark: rework commit message]
