Subject: [PATCH] Avoid SIGABRT on platform plugin initialization failure

If all platform plugins failed to initialize, Qt calls qFatal which in turn
calls abort. This causes SIGABRT and may generate a coredump.

In the most common case it's because the connection to the display (Wayland,
X11, whatever) is missing or failed, and a coredump will not help analyzing
that at all.
