Revert "libobs: Add UI-independent plugin search paths"

This reverts commit 99c674e41f.

These commits were originally added to allow multiple user interfaces to
use the same plugins, but I soon realized that multiple user interfaces
can use multiple libobs versions, so each user interface should have its
own set of plugins to manage.  Some user interfaces may not wish to use
certain plugins anyway, so this fixes that issue as well.
