netperf: Correct license flags

   From: Mark Hatle <mark.hatle@windriver.com>

   I was helping someone with building netperf from meta-networking last
   night, and stumbled on what I think is a bug.

   SUMMARY = "A networking benchmarking tool"
   DESCRIPTION = "Network performance benchmark including tests for TCP,
   UDP, sockets, ATM and more."
   SECTION = "console/network"
   HOMEPAGE = "http://www.netperf.org/

"
   LICENSE = "netperf"
   LICENSE_FLAGS = "commercial"

   In the above, the LICENSE_FLAGS are set to 'commercial'.  I think this
   is incorrect.  It should be set to 'non-commercial'.

   There is a subtle difference between them which is why I think it's a
   bug...

   commercial -- there are some commercial requirements necessary to use
   this recipe in a commercial device... you are responsible for
   understanding them and doing whatever is necessary... (for
   non-commercial devices you can likely use it...)

   non-commercial -- this item is restricted to non-commercial users only.
   As in the case of netperf, the license says it's only for
   non-commercial use.

   So anyway, my suggestion is to simply change the value of the flag.
