GH-808: Add ZEEK_VERSION_NUMBER definition to zeek-config.h

Browse source 
This is the result of (major * 10000 + minor * 100 + patch), for example
3.1.2 becomes 30102.  This definition may be helpful for external code
that requires conditional compilation to support multiple Zeek
versions with differing APIs.
