Let scripts set/preserve port.version.service_fp

Browse Source 
Previously, calling nmap.set_port_version would delete a service
fingerprint if it existed. Now, setting probestate to anything but
"hardmatched" will preserve the fingerprint, if it exists. This allows
scripts (like http-server-header) to use "softmatched" to set version
info but still encourage users to submit fingerprints.
