brave-browser: sometimes geolocation no longer working (uses old endpoints)

Description

Starting with 1.14.x geolocation no longer works on macOS Mojave. It seems on 1.13.x and prior we were proxying thru location.brave.com, however with 1.14.x that proxy doesn’t seem to be there so geolocation fails.

Note, this is working for @kjozwiak using Catalina. Additionally, @btlechowski checked Linux and Windows and geolocation is working there as well.

Steps to Reproduce

1. Install any of the following: 1.14.81, 1.14.84 (current release), 1.15.x, 1.16.x.
2. Navigate to https://browserleaks.com/geo and/or https://html5demos.com/geo/.
3. Allow location from prompt.

Actual result:

Location service fails:

Expected result:

Should work as it did in 1.13.86:
