Check for enabled / working Port scanner plugin

The script reports if: - a custom scan configuration is in use without having a Port scanner from the 'Port scanners' family enabled. - a port scanner plugin was running into a timeout. - a required port scanner (e.g. nmap) is not installed.

Based on the script output please: - add a Port scanner plugin from the 'Port scanners' family to this scan configuration. Recommended: Nmap (NASL wrapper). - either choose a port range for this target containing less ports or raise the 'scanner_plugins_timeout' scanner preference to a higher timeout. - install the 'nmap' binary/package or make it accessible to the scanner.
