SystemMonitor: Don't try and show process window with nothing selected (#7221)

Browse Source 
When right-clicking with no selected row in the process list,
SystemMonitor would still show a context menu. This disables
the context menu if index is invalid and also disables Alt+Enter
so that build_process_window() is never called with a PID of -1.

Fixes #7167.
