Subject: [PATCH] configure: make quiche require quiche_conn_send_ack_eliciting

curl now requires quiche version >= 1.17.1 to be used and this function
was added in this version and makes a convenient check.

This requirement is because this is the lowest quiche version that
supports peer-initiated key updates correctly.

Closes #10886
