nixos/test-driver/Logger: Replace invalid UTF-8
Regression introduced by d84741a4bfb6ed2531ec7154479c147d2c9a737c.

The mentioned commit actually is a good thing, because we now get the
output from the X session.

Unfortunately, for the i3wm test, the i3-config-wizard prints out the
raw keyboard symbols directly coming from xcb, so the output isn't
necessarily proper UTF-8.

As the XML::Writer already expects valid UTF-8 input, we assume that
everything that comes into sanitise() will be UTF-8 from the start. So
we just decode() it using FB_DEFAULT as the check argument so that
every invalid character is replaced by the unicode replacement
character:

https://en.wikipedia.org/wiki/Specials_(Unicode_block)#Replacement_character

We simply re-oncode it again afterwards and return it, so we should
always get out valid UTF-8 in the log XML.

For more information about FB_DEFAULT and FB_CROAK, have a look at:

Build Status Issue Stats Issue Stats

Nixpkgs is a collection of packages for the Nix package manager. It is periodically built and tested by the hydra build daemon as so-called channels. To get channel information via git, add nixpkgs-channels as a remote:

% git remote add channels git://github.com/NixOS/nixpkgs-channels.git

For stability and maximum binary package support, it is recommended to maintain custom changes on top of one of the channels, e.g. nixos-16.03 for the latest release and nixos-unstable for the latest successful build of master:

% git remote update channels
% git rebase channels/nixos-16.03

For pull-requests, please rebase onto nixpkgs master.

NixOS linux distribution source code is located inside nixos/ folder.
