Bruce Richardson bbaf917565 kni: flag deprecated status at build time 
To ensure all users are aware of KNI's deprecated status at build time,
this library is marked as a deprecated library: the library is disabled
by default. It can be re-enabled by setting disabled_libs to the empty
string (or other string not including 'kni').

The dependent NIC driver, drivers/net/kni, is disabled accordingly as it
depends on the library.

NOTE: This is part of the deprecation process for KNI agreed by the DPDK
technical board.[1]
