[vtkusers] HeaderTest failures

[Kevin Dixon]

Found the issue - these tests run just fine when the Python executable is
3.x.
When Python 2.x is used they fail because the Python script
HeaderTesting.py fails to strip newlines/carriage returns from the class
names parsed from the headers.
Simple fix is to alter the script to strip out control characters.
