The first argument for snprintf is the buffer and the 2. one is the
size. Fix the order. This broke the lock application.

Kernel setting `/proc/sys/kernel/pid_max` can be set up to 4194304 (7
digits) which will cause buffer overflow in busbox lock patch, this
often happens when running in a rootfs container environment.
This commit enlarges `pidstr` to 12 bytes to ensure a sufficient buffer
for pid number and an additional char '\n'.

The "new style" busybox applet approach moves all config and build
definitions related to an applet to its .c file. This makes the
patches easier to maintain, as they only add new files to the busybox
build directory, without modifying BusyBox files.

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.
