http.c: Do not return partial if no file is setHEADv0.6.0master

Whereas libweb does support returning partial transfers [1], it only
does so limited to file transfers because it can be difficult or
impossible to perform a partial request for what can be otherwise
dynamically generated content.

Previously, libweb naively accepted any range request from the client
and silently replaced the response status to "206 Partial Content". [2]
However, if no FILE * had been specified by the application,
adjust_partial would treat this as a fatal error, because libweb assumed
this as a programming error by the application.
