pkg/terminal: Fix exit status

Browse Source 
During a debug session if the process exited and then the user quit the
debug session, the process exit message would display again and Delve
would exit non-zero (specifically with exit code 1) despite nothing
going wrong.

This patch fixes this so that Delve exits with a clean 0 status and the
process exit message is not printed yet again.
