fugu: Remove wifi vendor HAL

The vendor HAL is non-functional on fugu today because of a file system
capability error. Since we have a mechanism to selectively disable wifi
hal now, use it and remove the wifi hal service from device.mk and from
the HIDL manifest.

Bug: 37483427
Test: Device boots up and able to connect to wifi networks.
