vim-patch:8.0.1398: :packadd does not load packages from the "start" directory (#8762)

Problem:    :packadd does not load packages from the "start" directory.
            (Alejandro Hernandez)
Solution:   Make :packadd look in the "start" directory if those packages were
            not loaded on startup.
