tools: acrntrace: Make all python scripts python3 module

The trend is to focus on Python3 and deprecate Python2. This patch make all the
acrntrace related scripts as Python3 module.

  - Add parentheses to all the print as Python3 required.

  - Remove suffix L and long() Python3 has deprecated. Python3 will treat all
    intergers as long.

  - Replace has_key() with "key in .keys()" because has_key() has been deprecated.

  - Other minor fixes.
