meson: remove prepend_libdir_vk option

The option is always true for all distributions that build Mangohud.
While only the in-tree PKGBUILD disables it for undocumented reasons.

In practise the option will be enabled across the board - in different
manner, with latter commit. But for now, just remove it.
