Generate the list of installed files in recovery image.

We're putting more files into recovery image since adding the support
for using shared libraries in recovery. This CL generates the list of
files to help understand the exact files installed there and their
sizes.

Bug: 112494634
Test: `m dist` with aosp_marlin-userdebug. Check the generated file at
      out/dist/installed-files-recovery.{txt,json}.
