tests: Extend RRM neighbor request testing

This uses a new testing mode in hostapd to allow RRM neighbor request
transmittion to be tested. For the second part of the test case to be
executed, mac80211_hwsim needs to be modified to claim support for the
required RRM capabilities (that change is not yet in Linux kernel).
