cleanup: specify never-interactive option for flex scanner

We never parse configuration interactively.  That's just as well,
because without "%option never-interactive" flex generates a redundant
declaration of isatty which upsets -Wredundant-decls.

This is a bug in flex IMO but the workaround is fine for secnet.
