Bug 1558782 [wpt PR 17289] - Revert "Ignore lint failures until we import a rev with them fixed", a=testonly

Automatic update from web-platform-tests
Revert "Ignore lint failures until we import a rev with them fixed" (#17289)

This reverts https://github.com/web-platform-tests/wpt/pull/13396.

These exact lines are also in the "Duplicate filename where there's no
actual merging" section of the file.

The change came from https://hg.mozilla.org/mozilla-central/rev/f23487d9ab99d486fe3ab7f261e4d4e0bf1172ae
where those lines were present, although they were present in WPT when
that change was upstreamed.
