Add args to the installd commands for profiler usage. Make installd create the profile files and allow apps to write to them. The profile files are in /data/dalvik-cache/profiles. This central location is needed due to permissions issues with dex2oat reading from an app's data directory. The solution is to put the profile file in a directory owned by the install user and make the file writeable by the shared group id of for the app. The app can read and write to these files only in the profiles directory. The 'system' user also needs to be able to read the files in order to determine the amount of change to the file over time.
