Ensure the UTF-8 string for a xcb_keycode_t has the correct length.

On my platform (Archlinux, libxcb 1.11-1) and a recent build of Qt dev
I noticed that writing anything to a QLineEdit was broken, as not only
the character for the pressed key was inserted, but also what looks
like whitespace. A simple debug program showed that a "\u0000" is
appended to every character in the QString text associated with a
QKeyEvent, which brought me to QXcbKeyboard::lookupString.

The QByteArray to QString conversion using QString::fromUtf8 includes
the \x00 byte at the end of the buffer.

By leveraging the size returned by the xcb API and passing that to
QString::fromUtf8 we can prevent this problem from arising.
