[PATCH 2/3] rt-tests: Add SPDX identifiers and fix documentation issues

Add SPDX-License-Identifier: GPL-2.0-or-later to the following files
that were missing license identifiers:
- get_pylib.py
- Dockerfile
- MAINTAINERS
- README-Dockerfile
- src/pi_tests/README
- src/queuelat/README
- src/queuelat/targeted-ipi/README

Additionally, fix documentation issues:

In README-Dockerfile:
- Fix spelling: "imbiguous" → "unambiguous"
- Correct project references: "rteval" → "rt-tests" in directory name,
  container image name, and section heading to accurately reflect that
  this is rt-tests documentation

In src/pi_tests/README:
- Fix spelling: "inheritence" → "inheritance"
- Fix typo: "one one processor" → "on one processor"
- Fix spacing: "fetchthe" → "fetch the"
- Fix option: "--duraton" → "--duration"

 ## Introduction
-This README provides detailed instructions for setting up an rt-tests container using Docker or Podman. This Dockerfile will pull a current copy of your code (plus all of your changes) and compile it into a container image for you to test with. This will give you an imbiguous way to test your changes, assuming you are running on a semi-modern host OS. The rt-tests container can be used to test any of the subpackages found under the rt-tests project, but is mainly intended for hwlatdetect and cyclictest.
