Make the fingerprint enroll progress bar scalable by moving it to a
single FingerprintProgressBar view and make it fill the remaining
space.
- The background fingerprint icon was changed to include the padding
internally so it can be added as the background directly onto the
progress bar view.
- The icon in landscape mode is also fixed to use the fingerprint
icon rather than the lock icon.
