bug#31397: 27.0.50; Emacs doesn't call package-initialize if there's no elpa directory

I installed an alternative patch which doesn't fully initialize package,
but does make package-installed-p work even if package-initialize hasn't
been called yet.

Good question.  I hope the answer is none, and I think if we find one,
we should change it so it initializes the relevant vars automatically.
