AudioService: correct BT A2DP abs volume curve for low levels

Browse Source 
When BT A2DP absolute volume is used, media volume steps 1,2,3 are
controlled by the framework. This change makes step 1 more useable
by making it slightly louder, and decreases the volume change step
for 2 and 3.

Bug: 176463546
Test: use A2DP device with abs vol, and change media vol to 1/2/3
