Remove "Prevent WebRTC from leaking local IP address" setting from uBO for Firefox for Android

[efk4]

Prerequisites

• I verified that this is not a filter list issue. Report any issues with filter lists or broken website functionality in the uAssets issue tracker.
• This is NOT a YouTube, Facebook or Twitch report. These sites MUST be reported by clicking their respective links.
• This is not a support issue or a question. For support, questions, or help, visit /r/uBlockOrigin.
• I performed a cursory search of the issue tracker to avoid opening a duplicate issue.
• The issue is not present after disabling uBO in the browser.
• I checked the documentation to understand that the issue I am reporting is not normal behavior.

I tried to reproduce the issue when...

• uBO is the only extension.
• uBO uses default lists and settings.
• using a new, unmodified browser profile.

Description

According to the uBO wiki (https://github.com/gorhill/uBlock/wiki/Dashboard:-Settings#prevent-webrtc-from-leaking-local-ip-address), the "Prevent WebRTC from leaking local IP address" setting still exists in Firefox for Android "because obfuscation is still not implemented." According to the issue linked from the wiki (https://bugzilla.mozilla.org/show_bug.cgi?id=1581947), Firefox has implemented obfuscation in pre-release builds and is targeting version 149 for stable release. Assuming that I have interpreted everything correctly, the "Prevent WebRTC from leaking local IP address" setting can now be removed from uBO for all browsers.

Steps to Reproduce

The "Prevent WebRTC from leaking local IP address" setting is present in uBO for Firefox for Android because that browser did not support mDNS hostname obfuscation.

Expected behavior

Support for mDNS hostname obfuscation is planned for Firefox 149, so the "Prevent WebRTC from leaking local IP address" setting may be removed.
