system: use signalfd for dlt-system

1: Move the call of pthread_sigmask in dlt-qnx-systems main before DLT_REGISTER_APP, because this already spawns a thread, what was done without applying pthread_sigmask before.
2: Replaced all threads in dlt-system, that are spawned for each feature, through one poll. This poll waits for a file descriptor event, that triggers the feature routine, that was executed before in the thread. Done this for following processes:

* reading syslog and journal
* frequently reading logfile and logprocess
* triggering filetransfer, if a file was added/changed in watched directory
* checking watchdog timer of systemd service file with defined intervall
