sepolicy: Rename hal_uwb -> hal_uwb_vendor

Since we are now creating an AOSP HAL for uwb. Rename Pixel specific
internal UWB HAL from Android S to hal_uwb_vendor to avoid conflicts
with the AOSP HAL sepolicy rules that are going to be added in
Android T.

Android S Architecture:
|Apps | AOSP API | Vendor Service | Vendor HAL Interface | Vendor HAL
Implementation | Vendor driver/firmware

Android T Architecture:
|Apps | AOSP API | AOSP Service | AOSP HAL Interface | Vendor HAL
Implementation | Vendor driver/firmware

Ignore-AOSP-First: Dependent changes in internal-only projects.
