bgpd: Do not explicitly print MAXTTL value for ebgp-multihop vty output

Browse Source 
1. Create /etc/frr/frr.conf
```
frr version 7.5
frr defaults traditional
hostname centos8.localdomain
no ip forwarding
no ipv6 forwarding
service integrated-vtysh-config
line vty
router bgp 4250001000
  neighbor 192.168.122.207 remote-as 65512
  neighbor 192.168.122.207 ebgp-multihop
```

2. Start FRR
`# systemctl start frr
`
3. Show running configuration. Note that FRR explicitly set and shows the default TTL (225)

```
Building configuration...

Current configuration:
!
frr version 7.5
frr defaults traditional
hostname centos8.localdomain
no ip forwarding
no ipv6 forwarding
service integrated-vtysh-config
!
router bgp 4250001000
 neighbor 192.168.122.207 remote-as 65512
 neighbor 192.168.122.207 ebgp-multihop 255
!
line vty
!
end
```
4. Copy initial frr.conf to frr.conf.new (no changes)
`# cp /etc/frr/frr.conf /root/frr.conf.new
`
5. Run frr-reload.sh:

```
$ /usr/lib/frr/frr-reload.py --test  /root/frr.conf.new
