bitbake: fetch2: Drop DL_DIR fallback for local file fetcher

A long time ago, we made DL_DIR a final fallback for the local fetcher.
Since then we added checksum support and task hashes and the world
has changed. There were warnings added some time ago if this fallback
triggers and it is now time to drop it entirely.

The original use case was for sstate however the sstate code now sets
FILESPATH correctly so DL_DIR is no longer needed.

There have been a few small bugs exposed by this change, missing mkdir
calls and some minor test issues that needed tweaks. In general this
simplifies and improves the fetcher code flow though.

This completes a cleanup that ensures local files are correctly covered
at parse time which ensures rebuilds and reparses happen at the right
times.
