Felix Fietkau 3670f4128d busybox: lock: implement -n "Fail rather than wait"
lock -n is similiar to flock -n. If the lock was already taken,
fail with exit code = 1 and write error message to stderr.

example:
if ! lock -n /tmp/foo ; then
	echo lock exits.
else
	echo lock was free. But is locked now.
fi
> lock was free. But is locked now.
> lock exists.
