sockstat on freeBSD can hang on getpwuid()

In certain situations, a system can be joined to a directory service and consequently lose access to said directory service (i.e externel network goes down, DNS server goes down etc etc). In this scenario, getpwuid() can take a LONG time to run since it will try to resolve the numeric UIDs to user names. There is no flag to disable this option but one can be added quite trivially.
