patch 8.2.2442: automatic GUI selection does not check for GTK 3

Commit: https://github.com/vim/vim/commit/f272ae12ac064856b710046393d5bf9b1670076d

    patch 8.2.2442: automatic GUI selection does not check for GTK 3

    Problem:    Automatic GUI selection does not check for GTK 3.
    Solution:   Make SKIP_GTK3 empty for automatic GUI support.  Set SKIP_GTK3 to
                YES when checking for GTK2.
