multi: rename nolint:lll to nolint:ll

Find and replace all nolint instances refering to the `lll` linter and
replace with `ll` which is the name of our custom version of the `lll`
linter which can be used to ignore log lines during linting.

The next commit will do the configuration of the custom linter and
disable the default one.
