Assign issue number to wpt -webkit-line-clamp tests

These are tests added by Mozilla. Most tests show different
behavior for `webkit-line-clamp` between Blink and WebKit.
Gecko seems to have landed in Nightly[1].

Blink failures seem related with inline continuations. WebKit
renders nothing for most tests, which I can't explain what is
going on.
