It does not work because the VirtualBox binaries are now setuid root.
VirtualBox, VBoxSDL, VBoxHeadless and so on are small stubs running
setuid root. After doing several consistency checks and after opening
the handle to kernel driver, the privileges are dropped. LD_LIBRARY_PATH
does not work with setuid root binaries.
