WindowsEveryonePrincipal : update regex for FR

"Everyone" in a french Windows is "Tout le monde".
Thus, the line.split(" ") returns only "Tout" and putBlob() throws an exception.
The modified regex search for the first two consecutive white char to return the name.
Windows's whoami returns a bunch of 0x20 between the name and the type.
