remote-curl: use error instead of fprintf(stderr)

We usually prefix our error messages with "error: ", but
many error messages from remote-curl are simply printed with
fprintf. This can make the output a little harder to read
(especially because such message may be intermingled with
errors from the parent git process).

There is no reason to avoid error(), as we are already
calling it many places (in addition to libgit.a functions
which use it).

While we're adjusting the messages, we can also drop the
capitalization which makes them unlike other git error
messages.
