server: container_remove: ignore not existent exit file
Found out that during OpenShift testing, node was trying to remove
containers (probably in a bad state) and was failing the removal with
this kind of error:

E0828 13:19:46.082710    1235 kuberuntime_gc.go:127] Failed to remove
container
"e907f0f46b969e0dc83ca82c03ae7dd072cfe4155341e4521223d9fe3dec5afb": rpc
error: code = 2 desc = failed to remove container exit file
e907f0f46b969e0dc83ca82c03ae7dd072cfe4155341e4521223d9fe3dec5afb: remove
/var/run/crio/exits/e907f0f46b969e0dc83ca82c03ae7dd072cfe4155341e4521223d9fe3dec5afb:
no such file or directory

I believe it's ok to ignore this error as it may happen conmon will
fail early before exit file is written.
