RequestServer: Do not crash on Gemini responses

Browse source 
Starting a gemini request creates a pipe for the output stream for the
response, and a Core::Stream::File object is created from that pipe.
Previously, the length of the response was computed by calling
output_stream.size() which used lseek on the file descriptor. Doing that
returned an error from lseek. Computing the value by counting the
received bytes (via Gemini::Job::response_length) avoids that crash.
