locking/atomics: Use sed(1) instead of non-standard head(1) option
POSIX says the -n option must be a positive decimal integer. Not all
implementations of head(1) support negative numbers meaning offset from
the end of the file.
Instead, the sed expression '$d' has the same effect of removing the
last line of the file.
