Merge bitcoin/bitcoin#24134: build: Fix zeromq package when cross-compiling

f13e642c83 build: Disable valgrind when building zeromq package in depends (Hennadii Stepanov)
b970f03bea build: Disable libbsd when building zeromq package in depends (Hennadii Stepanov)
77899991b1 build: Update netbsd_kevent_void.patch (Hennadii Stepanov)

Pull request description:

  Since v4.3.3 (068385c951) `libzmq` uses `libbsd` by default.

  This PR disables `libbsd` explicitly, as it's not a part of our depends. Zeromq will fallback to its internal `strlcpy` implementation.

  Otherwise, on systems with installed `libbsd-dev` package the `zeromq` package build system erroneously detects `libbsd` package from the host system:

  ```diff

   Libs.private:  -lpthread
  -Requires.private:
  +Requires.private:  libbsd
   Cflags: -I${includedir}
  ```

  This causes the `configure` fails to detect the `zeromq` package:
  ```
  configure: WARNING: libzmq version 4.x or greater not found, disabling
  ```

  Other minor improvements:
  - fixed `netbsd_kevent_void.patch` offset
  - disabled valgrind as it's used in unit tests which we do not run:
