Jouni Malinen 8e416cecdb tests: Make key-lifetime-in-memory more robust for GTK check 
The decrypted copy of a GTK from EAPOL-Key is cleared from memory only
after having sent out CTRL-EVENT-CONNECTED. As such, there was a race
condition on the test case reading the wpa_supplicant process memory
after the connection. This was unlikely to occur due to the one second
sleep, but even with that, it would be at least theorically possible to
hit this race under heavy load (e.g., when using large number of VMs to
run parallel testing). Avoid this by running a PING command to make sure
wpa_supplicant has returned to eloop before reading the process memory.
This should make it less likely to report false positives on GTK being
found in memory.
