fa4620be782c2bf6b5ffddf4f671194fdd1536f3 util: Add UnintrruptibleSleep (MarcoFalke)

Pull request description:

  We don't use the interruptible feature of boost's sleep anywhere, so replace it with the sleep in `std::thread`

    ACK fae86c38bca5c960462e53975314a0749db5d17d - note that an instance of `DHAVE_WORKING_BOOST_SLEEP_FOR` was missed in the [linter](https://github.com/bitcoin/bitcoin/blob/master/test/lint/extended-lint-cppcheck.sh#L69), but that can be cleaned up later.
