* busybox: fix busybox lock applet pidstr buffer overflow
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'.

* busybox: Fix snprintf arguments in lock
The first argument for snprintf is the buffer and the 2. one is the
size. Fix the order. This broke the lock application.
