fix: wrong variable names in MQTT startup log

[haydaramru]

Summary

The startMqtt() function in run.sh defines the variables epollTimeoutInterval and maxPacketsPerClient, but the echo statement incorrectly references $epollTimeout and $maxPackets. As a result, the MQTT startup log displays empty values:

Starting mqtt_pit with port=1883 maxEvents=4096 epollTimeout= pubrelInterval=10000 maxPackets= maxNoClients=4096

Fix: Update the echo statement to reference the correct variable names so the log output accurately reflects the values passed to the binary:

Starting mqtt_pit with port=1883 maxEvents=4096 epollTimeoutInterval=5000 pubrelInterval=10000 maxPacketsPerClient=50 maxNoClients=4096
