Increase certain waiting time window in gpu_device_plugin e2e_node test.

Kubelet restart process seems to get a bit slower recently. From running
the gpu_device_plugin e2e_node test on GCE, I saw it took ~37 seconds
for kubelet to start CM DeviceManager after it restarts, and then took
~12 seconds for the gpu device plugin to re-register. As the result,
this e2e_node test fails because the current 10 sec waiting time is too
small. Restarting a container also seems to get slower that it sometimes
exceeds the current 2 min waiting time in ensurePodContainerRestart().
This change increase both waiting time to 5 min to leave enough space
on slower machines.
