Add support for FreeBSD.

Use readchar_linux on FreeBSD too, like on Linux and Darwin. This seems to run fine.

Hello, I added your commit to #79. Could you please run the manual testscript (in tests/manual-test.py) on a FreeBSD system and verify that it works with most characters/keys?

also if you want to you could remove the platfrom checks here:

https://github.com/Cube707/python-readchar/blob/f20f57f0e01bbda4bf6ca55035c87b5b4dbcbbfb/tests/posix/conftest.py#L4-L13

and check if the tests complete on a FreeBSD system as well.

Sorry that I missed this earlier. I've now done this and all of the tests pass... I can submit that as a separate pull request.

[trombonehero]

I've created a pull request (#86) to run the tests on *bsd* platforms.

Great, if you have the time it would be amazing to have some screenshots here of whats working on FreeBSD to have it documented for the future. But no pressure, if you don't have the time / can't be bother to do it, the issue is allready closed and will just stay undocumented...
