doc: Update build-openbsd for 0.13.0+ and OpenBSD 5.9

- Python 3 now supported.

- Bump boost version to 1.61 - one boost patch no longer needed.

- All checked with OpenBSD 5.9, except for the clang part, I left this
  as-is for someone adventurous.

- Mention overriding resource limits, OpenBSD's default ulimit does not
  suffice for building Bitcoin Core with gcc 4.9.3.

The default C++ compiler that comes with OpenBSD 5.7 is g++ 4.2. This version is old (from 2007), and is not able to compile the current version of Bitcoin Core. It is possible to patch it up to compile, but with the planned transition to C++11 this is a losing battle. So here we will be installing a newer compiler.

You can install a newer version of gcc with:

```bash
pkg_add g++ # (select newest 4.x version, e.g. 4.9.2)
pkg_add g++ # (select newest 4.x version, e.g. 4.9.3)
```

This compiler will not overwrite the system compiler, it will be installed as `egcc` and `eg++` in `/usr/local/bin`.

### Resource limits

The standard ulimit restrictions in OpenBSD are very strict:

data(kbytes) 1572864

This is, unfortunately, no longer enough to compile some `.cpp` files in the project,
at least with gcc 4.9.3 (see issue https://github.com/bitcoin/bitcoin/issues/6658).
If your user is in the `staff` group the limit can be raised with:

ulimit -d 3000000

The change will only affect the current shell and processes spawned by it. To
make the change system-wide, change `datasize-cur` and `datasize-max` in
`/etc/login.conf`, and reboot.

### Building Bitcoin Core

**Important**: use `gmake`, not `make`. The non-GNU `make` will exit with a horrible error.
