port: fix build without KNI

Commit 9fc37d1c071c is missing a conditional in the dependencies,
causing builds to fail when KNI is not enabled:
    == Build lib/librte_port
      LD librte_port.so.3
    /usr/bin/ld: cannot find -lrte_kni
    collect2: error: ld returned 1 exit status

Fixes: 9fc37d1c071c ("port: support KNI")
