Media: Revert r51211 to restore ms-files.php assets.

r51211 accidentally introduced a fatal error for Multisite instances with `ms_files_rewriting` enabled. Reverting removes the error, and the original purpose of the commit can be solved in another way.

Props otto42, barry, ryelle, azaozz.
Fixes #53492. See #53475.
