I think it's fine to ignore that failure from tor_fd_seekend in this
case.  Actually, I'm not clear, looking at the code, why it's there at
all: it seems to me that O_APPEND should already put us at the end of
the file, right?  It's not clear to me why we mask out O_APPEND in
start_writing_to_file().  Maybe looking at the git logs will shine
some light on it...
