cask/audit: anchor cask audit regexps to url

[krehel]

• audit_hosting_with_livecheck matched sourceforge.net/, dl.devmate.com/ and rink.hockeyapp.net/ anywhere in the download URL, so a lookalike host, a mirror path or a query parameter that merely contained one of those hosts produced a false "Download is hosted on X, please add a livecheck" error.
• Anchor each regexp to the URL authority so it only matches when the download is actually served from that host. SourceForge keeps matching its downloads. and project subdomains.
• Continues the cleanup of these three regexps started in Escape dots in domain regexps #23799, which escaped their dots.
