[U-Boot,07/10] test/py: Manual python3 fixes

- Modern pytest is more visible in telling us about parameters that we
  had not described, so describe a few more.
- ConfigParser.readfp(...) is now configparser.read_file(...)
- As part of the "strings vs bytes" conversions in Python 3, we need to
  encode / decode our pipes in a few areas, use utf-8 for this.
- Fix a typo noticed while doing the above ("tot he" -> "to the").

This patch breaks

./test/py/test.py --bd=qemu-arm64 --build-dir=.
