Matthew Jones fe026fef47 Inspector: Check if RemoteProcess is_inspectable
The previous check of looking at `/proc/PID` was not working, it would
always fail even if the process was indeed inspectable.

Commit 70117781 introduced a new IPC for asking InspectorServer whether
or not a given `pid` is actually inspectable.

If a process is not inspectable, the `GUI::ProcessChooser` is
redisplayed if it was previously displayed, otherwise it exits.
