SSL: fixed unexpected certificate requests (ticket #2008).

Using SSL_CTX_set_verify(SSL_VERIFY_PEER) implies that OpenSSL will
send a certificate request during an SSL handshake, leading to unexpected
certificate requests from browsers as long as there are any client
certificates installed.  Given that ngx_ssl_trusted_certificate()
is called unconditionally by the ngx_http_ssl_module, this affected
all HTTPS servers.  Broken by 699f6e55bbb4 (not released yet).

Fix is to set verify callback in the ngx_ssl_trusted_certificate() function
without changing the verify mode.
