Uses "blkid" tool to extract metadata from an inserted volume, and reports it up to the framework. This needs to happen in vold, since only the FUSE-wrapped volume is visible to userspace. Remove autorun sanitization, since FUSE takes care of this now. Bug: 11175082 Change-Id: Ie69b38011ad6011bfb50e40d4f35a29e02150c19
