hostname: do not use gethostbyname() for "hostname -s"
There's no reason to call gethostbyname() on the value returned
by uname() when asked just for a short name of a host. This may
also be wrong, when uname is set to one value, but in /etc/hosts
(or elsewhere) the "canonical" name is different. This is often
the case for localhost entry in /etc/hosts:
127.0.0.1 localhost myname
With this content of /etc/hosts, and uname being set to myname,
busybox hostname -s will return localhost, while regular
hostname utility returns myname.
Fix this by not calling gethostbyname() for the simple
'hostname -s' use.
