recog_match does not support multiline input banners

[jhart-r7]

recog_match can read banners from STDIN or from a file passed on the command line, but assumes that each line of input is a banner. This complicates working with multiline banners, like NTP:

In this case, /tmp/f contains an example NTP fingerprint taken verbatim from our fingerprints:
