[PATCH v2] sstate: add manifest info for shared file matches

[Saul Wold <sgw@linux.intel.com>]

Present the manifest file that contains the matches for
files being installed to a location that already contains
that file. This will help to determine which is the correct
recipe to fix when this occurs.
