Wifi: omit FILS related vts tests if not supported

Supplicant FILS operation is independent from driver key management
driver support, i.e. even FILS is not supported in driver,
these APIs still could be used. These APIs are controlled by supplicant
CONFIG_FILS directly. To avoid inconsistent capability check, omit FILS
vts tests if any of driver and supplicant does not support it.
