tests: Wait for hostapd/wpa_supplicant to reply at start (concurrent)

Instead of waiting for a fixed duration, poll hostapd/wpa_supplicant
through the control interface until they are ready to reply in order to
avoid starting test case execution too early. This is like commit
b76579e0c09a1a763b70d63613377b407cbc405f but for the concurrent P2P test
cases that were forgotten from that commit.
