Subject: [PATCH] OutputPage: Remove support for non-existent /w/skins/common
 directory

Test Plan:
* Add calls `$this->addScriptFile( 'example.js' )` and
  `$this->addScriptFile( '/example.js' )` to top of OutputPage::output().
* Without this change, two `<script>` are added.
* With this change, only for the latter a script is added,
  and the former triggers a deprecation warning.

Bug: T71277
Bug: T181318
Change-Id: I0576ef09fafa4ba34d52d75f4211fcfa28f4f3b0
