pseudo: quiet diagnostics during startup for pseudo -d

When the client spawns a pseudo server, it starts out sending diagnostics
to stderr. This can be spammy in some cases with races during startup;
everything resolves, but we get scary-looking diagnostics. So shove
those into a log file.

+Subject: [PATCH 2/2] Use correct file descriptor
+
+So it turns out that pseudo_logfile() was returning 0 or -1, and
+pseudo_debug_logfile() was expecting it to be the correct file descriptor
+to use. And it's basically a mystery that any of that ever worked.
