do not use _apt for file/copy sources if it isn't world-accessible
In 0940230d we started dropping privileges for file (and a bit later for copy, too) with the intend of uniforming this for all methods. The commit message says that the source will likely fail based on the compressors already – and there isn't much secret in the repository content. After all, after apt has run the update everyone can access the content via apt anyway… There are sources through which worked before which are mostly single-deb (and those with the uncompressed files available). The first one being especially surprising for users maybe, so instead of failing, we make it so that apt detects that it can't access a source as _apt and if so doesn't drop (for all sources!) privileges – but we limit this to file/copy, so the uncompress which might be needed will still fail – but that failed before this regression. We display a notice about this, mostly so that if it still fails (e.g. compressed) the user has some idea what is wrong. Closes: 805069
