doctor: refactor the fixers so we can forward options and avoid duplicating efforts

[tido64]

Somewhat unrelated (and definitely not to be fixed in this PR), I looked briefly at the options that are passed to all CLI commands and it looks like they include this information. However, it doesn't look like they are properly forwarded to the individual fixers. It's a bit silly that we have to duplicate the effort to find this info again. Do we have an issue tracking this? cc @mikehardy @thymikee
