When the client or server crash the fifo will be dead
then the cleanup command hangs at
echo "quit" > client1.fifo
because the fifo is not responding and thus it is stuck there.
which causes the user to probably ctrl+c at some point
which then avoids client2 to be quit which might not have crashed
So this commit checks if a fail_client1.txt file exits and if it crashed
already it will skip the call to the broken fifo
See also Jupeyy's explanation in
https://github.com/ddnet/ddnet/issues/4294 for why we want to ignore
this:
> sadly components have no OnDestruct on anything like that
> so aslong it doesn't actually leak it's just non destructed memory
So it's something we allocate once for the entire client lifetime from
my understanding.

SUMMARY: AddressSanitizer: 411760 byte(s) leaked in 10 allocation(s).
As described in #5295, the integration test script waits for the client
to close before launching the next one. I don't know what causes this,
but disabling full-screen mode works around the issue.
I don't know if this is okay. @ChillerDragon?
Fixes#5295.
