build-sys: improve compat with older kernel headers

In 4.2 kernel headers, some netlink defines are missing that we need. missing.h
already can add them in, but currently makes this dependent on a definition
that these kernels already have. Change the check hence to check for the newest
definition in the table, so that the whole bunch of definitions as added in on
all kernels lacking this.
