Remove POSIX depedencies from the monitor example

Monitor is build on Autosar Classic. In the example code there is dependency to Posix libraries (sleep function and inet):
"qsrMonitor.c", line 31: fatal error #2330: cannot open source file "unistd.h"
#include <unistd.h>
"eventProcessor.c", line 28: fatal error #2330: cannot open source file
"arpa/inet.h"
#include <arpa/inet.h>

Also in the demo controller function, there is a warning about empty initializer:
warning #1981-D: empty initializer is non-standard
static StateMapItem stateMap[sizeof(itemStates) / sizeof(itemStates[0U])] = {};
