integration: remove --accept-routes from via steering routers

Browse Source 
Subnet routers that advertise routes must not accept peer routes.
With co-router visibility the HA primary's subnet appears in co-routers'
AllowedIPs, and --accept-routes installs a system route that conflicts
with local subnet forwarding.

Updates #3157
