netsniff-ng: nlmsg: Define NTF_* constants if not provided by kernel headers
NTF_SELF and NTF_MASTER might not be defined on older kernel versions (as is e.g. the case in the Travis CI build failing [1]). Fix this by conditionally defining all NTF_* constants. [1] https://travis-ci.org/netsniff-ng/netsniff-ng/jobs/68779130 Signed-off-by: Tobias Klauser <tklauser@distanz.ch>
