lib: Increase net_connect*() EADDRNOTAVAIL retries to 20

4 is too little, since on busy systems it's sometimes failing. These calls
should be pretty cheap, so lets try if 20 is enough.

It would be nice if this was configurable, but the only practical way right
now would be to use environment variable, which is a bit ugly. We could
try it next if 20 is still not enough.
