Michael Smith 0c72c98f91 IMPALA-9627: Update utility scripts for Python 3 ...

Updates utility scripts that don't use impala-python to work with Python
3 so we can build on systems that don't include Python 2 (such as SLES
15 SP4).

Primarily adds 'universal_newlines=True' to subprocess calls so they
return text rather than binary data in Python 3 with a change that's
compatible with Python 2.

Testing:
- built in SLES 15 SP4 container with Python 3
