net: samples: Reduce net pkt RAM usage

There are 174 RX/TX net pkt reserved, this make build fail
with some boards due to ram overflow (e.g quark_se_c1000).
Fix this by reducing NET_PKT RX/TX reserve to 100, which
seems fair enough for this use case. Moreover, don't think
there is any reason to have more NET_PKT than NET_BUF.
