xtensa-build-zephyr.py: add #pylint:disable=W0312,C0103,C0116

This reduces the number of warnings from about 600 to a more manageable
350.

Disable W0312 because the entire file uses tabs.
Disable C0103 because we have higher priority than naming conventions.
Disable C0116 because the script is small enough, shouldn't require
              pydoc everywhere.
