[android/process list] support showing process arguments

Summary:
The qfProcessInfo and qsProcessInfo packets currently don't set the processes' arguments, however the platform process list -v command tries to print it.
In this diff I'm adding the arguments as part of the packet, and now the command shows the arguments just like on mac.

On Mac:
