luci-mod-network: diagnostics: peg max traceroute hops to rpc timeout

Browse source 
In the worst case, traceroute might take up to 30s to complete when tracing
a completely unreachable path, due to the default limit of 30 hops multiplied
by the per-hop deadline of 1 second (-w 1).

Limit the maximum amount of hops to the configured rpc execution timeout,
20 second by default, in order to avoid running into timed out rpc requests.

Fixes: #5782
