Support i686-linux-android target for android-x86 emulator
The first commit allows `./mach build --target=i686-linux-android` to build successfully. The second commit is temporary as I attempt to find the cause of the mysterious crash that takes down the browser.

Avoid using WPT test runner to update the test manifest.
Our old code to update the test manifest relied on running no actual tests. This is now broken by d0a30f8821 (diff-c9390ffce43b4924882faf365b1bf136), so these changes duplicate Firefox's implementation to reduce risk of future breakage. This will allow automated WPT syncing to resume.
