BUG/MEDIUM: quic: properly take shards into account on bind lines

Shards were completely forgotten in commit f5a0c8abf ("MEDIUM: quic:
respect the threads assigned to a bind line"). The thread mask is
taken from the bind_conf, but since shards were introduced in 2.5,
the per-listener mask is held by the receiver and can be smaller
than the bind_conf's mask.

The effect here is that the traffic is not distributed to the
appropriate thread. At first glance it's not dramatic since it remains
one of the threads eligible by the bind_conf, but it still means that
in some contexts such as "shards by-thread", some concurrency may
persist on listeners while they're expected to be alone. One identified
impact is that it requires more rxbufs than necessary, but there may
possibly be other not yet identified side effects.

This must be backported to 2.7 and everywhere the commit above is
backported.
