Merge #18405: build: Drop all of the ZeroMQ patches

f642b49af73fedc6dc9af4ac299e4cfa80755583 build: Drop ZeroMQ patch for glibc < 2.12 (Hennadii Stepanov)
079df9609e6ed2a09949ebe5e98a179f61709801 build: Drop ZeroMQ patch for Mingw-w64 < 4.0 (Hennadii Stepanov)

Pull request description:

  This PR gets rid of the all patches for ZeroMQ:
  - the [Mingw-w64 5.0 (Ubuntu 18.04 bionic)](https://packages.ubuntu.com/bionic/mingw-w64) is used to build the [Windows](https://github.com/bitcoin/bitcoin/blob/master/doc/build-windows.md) binaries
  - it is safe to use `pthread_setname_np` since #17538 when the minimal `glibc` version is set to 2.17; see: https://github.com/bitcoin/bitcoin/pull/11986#issuecomment-366105050
