daemon: Do not exit when accept returns ECONNABORTED (#347)
Scan of port 3490 from a Linux machine by
'nmap -v -p 3490 -Pn IP_address_of_QNX_board' leads to dlt-daemon crash.
It is necessary to parse the code of the returned error in errno.
If errno = ECONNABORTED it means there was an attempt to scan port 3490
and on this error there is no need to exit the application by error.
Fix for the issue https://github.com/GENIVI/dlt-daemon/issues/341
