platform_system_core/adb/client/fastdeploy.cpp
Henry Daitx ee01c80afe Change --fastdeploy behaviour 
--fastdeploy does not require -r anymore, and reverts to a normal install
if the application is not already on the device.

Bug: 120828611

Test: mm -j72
Test: adb install --fastdeploy --force-agent --local-agent /mnt/raid/boat-attack-apk/boat-attack-swappy.apk
