Set ro.sf.lcd_density to 440

FP2's real LCD density is 440, 480 was used before because CTS requires
using one of the predefined buckets (the closest ones being 420 and
480). Android 9 adds a 440 bucket, so use it to fix some UI issues.

Issue: FP2P-419
Test: run cts -m CtsDpiTestCases -t android.dpi.cts.ConfigurationTest#testScreenConfiguration
