Look at servers->dynamiclookuparg for deciding if a server is dynamic.

The dynamiclookupcommand member of the _config_ of the server is being
set to NULL when it's copied in confserver_cb(), resulting in dynamic
discovery being done for realms that already have a server.

Patch from Fabian Mauchle.

Addresses RADSECPROXY-69.
