security/zeek: Update to 4.0.7

https://github.com/zeek/zeek/releases/tag/v4.0.7

Security fixes since 4.0.6:

• Fix potential hang in the DNS analyzer when receiving a specially-crafted packet. Due to the possibility of this happening with packets received from the network, this is a potential DoS vulnerability.

Other changes:

• Fix issue with broken libpcaps that return repeat packets, most notably the version provided with Myricom hardware.
