    build: simplify uninstall-hook target in root folder
    
    The way to check if $(pkglibdir) exists can be simplified to just
    check for its existence now. I guess `find` was used in combination
    with `wc` before because it could happen that there were leftover
    subfolders not properly uninstalled, which would make `rmdir` error
    out.
    
    However, this situation has been fixed in [1], so we can now
    assume that $(pkglibdir) doesn't contain any elements when this
    hook happens (if it contains any elements, it will be a bug in the
    build infrastructure, so with this `rmdir` would fail fast, which
    is a good thing).
