Per https://bugzilla.mozilla.org/show_bug.cgi?id=1654185#c6

These were originally masked due to an exception in
tools/lint/file-whitespace.html for the directory dom/media/tests, but we
don't need an exception for our new location (dom/media/webrtc/tests/mochitests)
if we fix these 3 files.

2 files had bad line endings (Windows vs Unix):
dom/media/webrtc/tests/mochitests/test_getUserMedia_cubebDisabled.html
dom/media/webrtc/tests/mochitests/test_getUserMedia_cubebDisabledFakeStreams.html

1 file had trailing whitespace:
dom/media/webrtc/tests/mochitests/test_peerConnection_threeUnbundledConnections.html

Thank you, I missed an eslint exception for the moved mochitest directory. I'll get it fixed!

Fixed the eslint exception for the moved directory:

This was originally excepted under dom/media/tests/** here:
https://searchfox.org/mozilla-central/rev/89d33e1c3b0a57a9377b4815c2f4b58d933b7c32/.eslintrc.js#235

I'm adding the exception for dom/media/webrtc/tests/** for the moved files.

I just added the media mochitest jobs to my old push and they passed. Let me push the same after my rebase.

Here is a run based on the error shown in Bug 1667271:
https://treeherder.mozilla.org/#/jobs?repo=try&revision=56a557e52bb54e8d98fac4948066487ed59562e6

I don't see the same issue, so I'm going to rebase and then collapse the changes for the manifest location change into pt 1.

Here are the windows7-32-qr opt/debug media mochitests failing without my changes on central:
https://treeherder.mozilla.org/#/jobs?repo=try&revision=f7b243056ffc4587bc71ebcc87272b3111a0e604

Here are the same tests failing after my changes in the same way:

fuzzy query: mochitest-media
https://treeherder.mozilla.org/#/jobs?repo=try&revision=3892acce0e0462c0b895a3ac20761fb2ce0cf5a6

Looks reasonable.
