keepalived: update print_unicast_peer_indent func

Added options min_ttl and max_ttl in section peer. These options are
supported by keepalived but were not supported by the uci implementation.

This allows accepting packets within a specific TTL range.

These options are optional and wouldn't affect any older configurations
during upgrade.
