Bro 2.5.5 does not build under 12.0-ALPHA10 due to openssl 1.1.1
in the base. Unbreak build by statically linking against
security/openssl. This is a stopgap until Bro 2.6 which supports
openssl 1.1 is released. It is currently in beta and due in a
few weeks.

Add missing NETMAP_DESC while we're here.
