gre: Introduce 'nohostroute' option
It is not always necessary to add a host route for the gre peer address. This introduces a new config option 'nohostroute' (similar to the option introduced for wireguard in d8e2e19) to allow to disable the creation of those routes explicitely. This is a backport from OpenWrt master. Signed-off-by: Adrian Schmutzler <freifunk@adrianschmutzler.de> Reviewed-by: Fabian Bläse <fabian@blaese.de>
