Ignore ambiguous variable names error from pycodestyle 2.6
This error is given for any use of variable called "l" (and also "I" and
"O", but we don't seem to have any of those) and it doesn't seem to be
worth changing this variable name in the tests code, as it's really not
that meaningful there anyhow, so just disable the warning to let the CI
builds, which now use pycodestyle 2.6, instead of 2.5 which didn't have
this error and which is still the latest available in Debian Sid, pass.
