perf top: Setup signals for terminal output

The TUI code setup standard signals handling, while the stdio display
code does not. This leads to premature termination of display thread
when signal is received and leaving terminal in wrong state.

Also adding terminal cleanup at the end of display thread, to ensure we
get the old terminal state in case of signal interruption.
