Fixes bug [YOCTO #1165] The /etc/init.d/skeleton doesn't work on minimal image, this is because of the pidofproc doesn't return "$?" correctly, so store $? in the variable status would fix it.

functions This file contains functions to be used by most or all
shell scripts in the /etc/init.d directory.
NOTE: The pidofproc () doesn't support the process which is a script unless
the pidof supports "-x" option. If you want to use it for such a
process:
1) If there is no "pidof -x", replace the "pidof $1" with another
command like(for core-image-minimal):
ps | awk '/'"$1"'/ {print $1}'
Or
2) If there is "pidof -x", replace "pidof" with "pidof -x".
pidofproc - print the pid of a process
$1: the name of the process
pidofproc () {
# pidof output null when no program is running, so no "2>/dev/null".
pid=`pidof $1`
status=$?
