This enables pre-associating (scanning) MAC address randomization for
Android. It uses the default 60 second expiry time.

This would need to have a Signed-off-by: line in the commit message as
described in the top level CONTRIBUTIONS file.

How has this been tested? I'm mainly interested in which Android
versions and Wi-Fi drivers were used.

I don't think I'd recommend using this preassoc_mac_addr=1 design since
it changes the MAC address of the netdev. Instead, I'd use the pre-scan
request mechanism to request driver to use random MAC addresses. This
can be configured with the MAC_RAND_SCAN control interface command.
