Fix yamllint line-length warnings.

This patch fixes yamllint's "line too long" (line-lenght) warnings
by ensuring all lines in YAML files have, at most, 160 characters.

If a line cannot be written as a multiline block, line-length rule
evaluation is disabled for the specific line, both on yamllint and
on ansible-lint.
