net: Use conftest to determime NAPI interface

Browse Source 
Add compile time tests to the conftest.sh script
to determine netif_napi interface check at compile
time for the kernel being used. This is beneficial
for working with 3rd party Linux kernels that may
have back-ported upstream changes into the kernel
and so the kernel version checks do not work.
