Revert "sepolicy: Permission changes for new wifi mainline module"

This reverts commit 3aa1c1725ea2b6fd452c5771629dcfc50a351538.

Reason for revert: Wifi services no longer plan to be a separate
APK/process for mainline. Will instead become a jar loaded from Apex.

Bug: 144722612
Test: Device boots up & connects to wifi networks
