Assure NULL terminated strings in flexradio file.
Various strncpy operations could result in a port pathname that is not a NULL terminated string as the allowed string length is the same size as the buffer per the strncpy manual page. This is corrected by assuring that the allowed length is FILPATHLEN - 1.Hamlib-1.2.15
