Add Fairphone 2 blobs check and makefile

Since Fairphone 2 proprietary blobs have been moved and they will be provided
as separate package this commit add a check in the build process to verify the
presence of blobs before continuing.

Change for Android 9: Print the get_blobs.py command line to simplify
downloading of missing blobs.
