hostapd: Allow FTM functionality to be published

Browse source 
Add configuration options that control publishing of fine timing
measurement (FTM) responder and initiator functionality via bits 70, 71
of Extended Capabilities element. Typically, FTM functionality is
controlled by a location framework outside hostapd. When framework is
activated, it will use hostapd to configure the AP to publish the FTM
functionality. See IEEE P802.11-REVmc/D7.0, 9.4.2.27.
