OpenNHRP DMVPN configuration clean after reboot if we have any IPSec configuration
To reproduce:
```
set interfaces ethernet eth1 address '192.0.2.14/24'
set interfaces ethernet eth1 description 'WAN'
set vpn ipsec esp-group group-ESP lifetime '3600'
set vpn ipsec esp-group group-ESP mode 'tunnel'
set vpn ipsec esp-group group-ESP pfs 'dh-group14'
set vpn ipsec esp-group group-ESP proposal 10 encryption 'aes128'
set vpn ipsec esp-group group-ESP proposal 10 hash 'sha1'
set vpn ipsec ike-group group-IKE close-action 'none'
set vpn ipsec ike-group group-IKE disable-mobike
set vpn ipsec ike-group group-IKE key-exchange 'ikev2'
set vpn ipsec ike-group group-IKE lifetime '28000'
set vpn ipsec ike-group group-IKE proposal 10 dh-group '14'
set vpn ipsec ike-group group-IKE proposal 10 encryption 'aes256gcm128'
set vpn ipsec ike-group group-IKE proposal 10 hash 'sha1'
set vpn ipsec interface 'eth1'
set interfaces tunnel tun100 address '192.168.250.4/24'
set interfaces tunnel tun100 encapsulation 'gre'
set interfaces tunnel tun100 parameters ip key '1'
set interfaces tunnel tun100 source-address '192.0.2.14'
set protocols nhrp tunnel tun100 cisco-authentication 'secret'
set protocols nhrp tunnel tun100 holding-time '30'
set protocols nhrp tunnel tun100 multicast 'dynamic'
set protocols nhrp tunnel tun100 redirect
set protocols nhrp tunnel tun100 shortcut
```
Check config before the reboot:
```
vyos@r1-right# cat /run/opennhrp/opennhrp.conf
# Created by VyOS - manual changes will be overwritten
interface tun100 #hub
cisco-authentication secret
holding-time 30
multicast dynamic
redirect
shortcut

vyos@r1-right# run reboot now
Broadcast message from root@r1-right on pts/1 (Fri 2024-03-01 15:46:09 EET):
The system will reboot now!
```
After reboot the file is clean:
```
vyos@r1-right:~$ cat /run/opennhrp/opennhrp.conf
# Created by VyOS - manual changes will be overwritten
vyos@r1-right:~$
```
Wihout `vpn ipsec` configuration, the file looks good.
