scripts: Fix E741 that pycodesyle is pointing out during syntax-check

With newer pycodestyle 2.6.0 (which is part of flake8-3.8.2) reports
the following pep violation during syntax-check:

../scripts/check-remote-protocol.py:95:9: E741 ambiguous variable name 'l'
    for l in err.strip().split("\n")

On all the distros we test on, this hasn't occurred yet, but with the
future update of flake8 it likely would. The fix is easy, just name the
variable appropriately.
