[vtkusers] A fix for MSVC warning D9025: overriding '/W1' with '/w'

[Niels Dekker - address until 2018]

Hi Cory,

Thank you! When I have time (hopefully before next Sunday), I'll try 
to contribute the patch via your gitlab contribution process. Is the 
process similar to ITK? And do you think I should create a "ticket" or 
"bug report" for this little issue?

If I can't get it to work (or if it takes me too much time), I hope 
someone else can do the patch for me, next week or so...

   Kind regards, Niels

PS Also thanks to Audrius for the support  :-)
