Merge bitcoin/bitcoin#32690: depends: fix multiprocess build on OpenBSD (apply capnp patch, correct SHA256SUM command)

8713e8060d depends: fix SHA256SUM command on OpenBSD (use GNU mode output) (Sebastian Falbesoner)
2d938720bd depends: add patch to fix capnp build on OpenBSD (Sebastian Falbesoner)

Pull request description:

  This PR fixes the multiprocess depends build for OpenBSD by applying upstream patch https://github.com/capnproto/capnproto/pull/2308 and switching the SHA256SUM command to output hash sums in the expected format (the default is BSD format [1], but we need GNU format [2], see commit message for details). Note that the hashing issue is only prevailing for packages defining the `$(package)_local_dir` variable (introduced in 5d105fb8c3, part of #31741), where the following line of the `fetch_local_dir_sha256` function leads to the wrong output:
  ae024137bd/depends/funcs.mk (L57)

  The first commit can be replaced with a simple capnp version bump once this is available in a release.

  Tested on OpenBSD 7.7 (x86_64) via
  ```
  $ gmake -C depends MULTIPROCESS=1 NO_BOOST=1 NO_LIBEVENT=1 NO_QT=1 NO_QR=1 NO_WALLET=1 NO_ZMQ=1 NO_USDT=1
  ```

  [1] example output: `SHA256 (/home/thestack/.vimrc) = 6ba69d100e8c5ca0488ded6293d4e5f740a6a5d5ace96cbcf0599c18d27389e4`
  [2] example output: `6ba69d100e8c5ca0488ded6293d4e5f740a6a5d5ace96cbcf0599c18d27389e4 /home/thestack/.vimrc`

Subject: [PATCH 1/2] In cidr.c++, include <netinet/in.h> on all non-Windows
systems
The motivation for this commit is to fix the build for OpenBSD,
but it may also solves the same potential problem for other systems
without causing any harm.

Subject: [PATCH 2/2] Don't set KJ_USE_KQUEUE on OpenBSD
OpenBSD doesn't support user event filters yet, hence
the build fails as it misses the symbol EVFILT_USER in
the kqueue implementation in async-unix.c++. Fix that
by not setting KJ_USE_KQUEUE on OpenBSD, so the poll()-
based implementation is used instead.
