Revert "Follow-up ee320648fd1: output mw-content-{ltr,rtl} unconditionally"

This reverts commit 143c81451eb841b8dfc886dcc6c5d794837b4fc2.

Applying mw-content-{ltr,rtl} to non-view pages caused problems, like
on the history page. MediaWiki:*.js pages always have ltr as their content
directionality, but the history page should be in the UI directionality
regardless of what the content directionality of the page is (since
none of the page content is even displayed!)
