[libc] Make LIBC_EXIT RPC code use quick exit

Summary:
This RPC call does the final exiting. The callbacks were handled on the
GPU side and this is only 'valid' in the pretend mode where we treat the
GPU like a CPU program. Doing this keeps us from crashing and burning
if people continue using the program while this is running as `exit`
would tear down the offloading library in memory and lead to segfaults.
This just drops everything where it is and lets the process manager
clean it up for us.
