Subject: bitbake: fetch2/local.py: Provide better debug output when fetch of a
 local file fails

When a fetch failure occurs for a local file, this patch ensures we print the
locations searched making it easier for the user to debug the problem.

(Bitbake rev: a461adbc5f09b41c771a7603370f6f2d1299ae8e)
