fdo#66718: Revert "fdo#46808, Adapt SystemClipboard UNO service to new style"

This reverts commit 2fe852386c9450014f84910b0a282d684f40b56a, see
<https://bugs.freedesktop.org/show_bug.cgi?id=66718#c8> for details.  (On master
towards LO 4.2, this will be addressed differently, by modifying
2fe852386c9450014f84910b0a282d684f40b56a instead of reverting it, so this
libreoffice-4-1 commit is not a cherry-pick of any master commit.)
