Add the required functions to change the thread name of the UST threads and add the -ust string at its end. This will help to identify LTTng-UST processes when analyzing the trace of a process.

Mistake that comes from the first version of the patch (I was including pthread there). I must have replicated the spacing of the FreeBSD elif when updating the patch and didn't see that mistake!
