Fix two issues with the current configuration:
* The log buffer was too small for the sample, causing part of the stats
printout to be dropped
* The sample set CONFIG_NET_CONFIG_NEED_IPV4 but did not actually set
any IPv4 address, nor enable DHCP, causing the NET_CONFIG
initialization failure.

This finishes refactor of splitting off net_config library name from
net_app library, started in c60df1311, c89a06dbc. This commit makes
sure that Kconfig options are prefixed with CONFIG_NET_CONFIG_
instead of CONFIG_NET_APP_, and propagates these changes thru the
app configs in the tree.
Also, minor dependency, etc. tweaks are made.
