Subject: [PATCH] mediawiki.util: Remove redundant IE8 support from addCSS()

Was added in 8eda03743c (2013) for IE8 support, but MW now
requires IE11+. The HTMLStyleElement.sheet property is available
in all supported browsers.

<https://caniuse.com/#feat=mdn-api_htmlstyleelement_sheet>

The method itself was introduced in 2010 (79618024c2 / r76324).
