Extend TLS/SSL port detection

Browse Source 
As mentioned in #1931 the port detection for nmap greppable files
leaves space for improvements.

Ths PR adds a pattern detection of ssl and https in the forth or fifth
parameter of an open port, so those ports will be added to a scan when
a nmap greppable output file is as input to testssl.sh .

Also it does minor code adjustments to utils/gmap2testssl.sh .
