Pad indication text to prevent clipping on side of screen.

Padding amount is the same as owner_info also shown on AOD screen.

Bug: 137627803
Test: Checked that text with more than 100 characters shown in
indication area wasn't clipped on side of screen. 100 characters was
used because face_acquired_sensor_dirty string has char limit of 100.
