Update @balena/lint to v7

This updates balena lint to the latest version to enable eslint support
and unblock Typescript updates. This is a huge number of changes as the
linting rules are much more strict now, requiring modifiying most files
in the codebase. This commit also bumps the test dependency `rewire` as
that was interfering with the update of balena-lint
