dlcservice: dlctool - Implement DLC unpacker

Unpacking a DLC image is even simpler and requires less manual 'cp'ing,
'mv'ing, and locating files from DLC specific paths.

This change implements the counterpart to dlctool 'packer'/deployer.
Also pass --mount_point so repeated force_delete works with imagelaoder
commandline tool.

[ Prerequisite ]
  # Install the DLC you want to modify.
  $> dlcservice_util --install --id=<ID>

[ Instructions on modifying a DLC on DUT ]
   - Step 1 -
  # On a DLC image which is installed/preloadable.
  $> dlctool --unpack --id <ID> <PATH>

  - Step 2 -
  # <PATH> will now have the 'unpacked' DLC <ID>.
  # Make changes to the files in <PATH>.

  - Step 3 -
  # To deploy the changes into rootfs + dlcservice.
  $> dlctool --id <ID> <PATH>

  - Step 4 -
  # Repeat Steps 2 and 3 as many times as you'd like.
