Uhm, doesn't look like Zlib to me; here's the license text extracted from
dragon4.c:

And here are the MIT and Zlib licenses:

I would say that the license is indeed MIT, which is what LICENSE.txt says:

Name: dragon4
Files: numpy/core/src/multiarray/dragon4.c
License: MIT
  For license text, see numpy/core/src/multiarray/dragon4.c
