Send actual BTM capability when the driver takes care of BSS selection

Browse source 
wpa_supplicant disables BTM capability in Extended Capabilities element
when wpa_supplicant selects a misbehaving MBO/OCE AP that uses RSN
without PMF, but this is disabling BTM support for whole ESS connection
lifetime though the BTM support can be enabled when the driver takes
care of BSS selection and selects/roams to a BSS which is MBO and OCE
specification compliant. Thus, always set the actual BTM capability in
Extended Capabilities element when the driver takes care of BSS
selection.
