gdb-v8-support.py: Fix old style print statement

Since python3 does not use the old print statement, it may not be able
to load gdb-v8-support.py script in gdb as below:

  (gdb) source tools/gdb-v8-support.py
    File "tools/gdb-v8-support.py", line 170
      print result
                 ^
  SyntaxError: Missing parentheses in call to 'print'

This fixes print statement for both python2 and python3.
