dmvpn: add required patches for FRR NHRP implementation

Patches are not active. To activate bth patches add their corresponding
file name to debian/patches/series.

From FRR docs:
nhrpd needs tight integration with IKE daemon for various reasons. Currently
only strongSwan is supported as IKE daemon. nhrpd connects to strongSwan using
VICI protocol based on UNIX socket (hardcoded now as /var/run/charon.vici).

strongSwan currently needs few patches applied. Please check out bot git
- https://git.alpinelinux.org/user/tteras/strongswan/log/?h=tteras-release
- https://git.alpinelinux.org/user/tteras/strongswan/log/?h=tteras
repositories for the patches.

+Subject: [PATCH] vici: add (deprecated) async parameter
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+This is obsoleted by the new "timeout=-1" option that achieves
+the same. Only for compatibility with old versions of quagga-nhrp.
