[libvirt PATCH] scripts: Fix E741 that pycodesyle is pointing out during syntax-check

[Erik Skultety]

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.

The weird thing is that E741 checking has been in pycodestyle since 2.1.0 [1],
we now have 2.5.0 and yet only 2.6.0 is complaining about it
