Fix confetty PTY handling in oneshot mode

Browse Source 
When asked to execute a command, do not mess with the terminal
in a way that would incur SIGTTOU when run in background.  This
means that a backgrounded confetty can actually exit rather
than block waiting to be run in foreground.  This won't work
with running a *console* in background, but that really doesn't
make any sense.
