gnutls-cli: handle binary data from stdin

[Vitaly Mayatskikh]

Hello!

gnutls-cli is used as TLS wrapper in several MUAs (like Gnus and
Wanderlust) to access secured IMAP mail servers. IMAP proto has
extension RFC4978 for traffic compression with deflate
method. However, gnutls-cli is pure text-oriented client, so it can't
handle binary data from stdin correctly.

This trivial patch fixes the problem.

P.s.: Please, keep me in Cc, I'm not subscribed to the list.
