vquic/ngtcp2.h: define local_addr as sockaddr_storage

This field needs to be wide enough to hold sockaddr_in6 when
connecting via IPv6.  Otherwise, ngtcp2_conn_read_pkt will drop the
packets because of the address mismatch:
  I00000022 [...] con ignore packet from unknown path

We can safely assume that struct sockaddr_storage is available, as it
is used in the public interface of ngtcp2.

Closes #6250
