bug#53527: 29.0.50; package-reinstall fails to initialize (enough of) package.el

This is one way to fix it.  Another would have been to call
`package--alist' instead of reference `package-alist' in
`package-reinstall'.  ...but that wouldn't have been an optimization,
since `package-install' inevitably calls `package--archives-initialize'
anyway.  This patch just makes it happen earlier.

Subject: [PATCH] Fix calling `package-reinstall' just after quick
 initialization.

* lisp/emacs-lisp/package.el (package-reinstall): call
`package--archives-initialize', just like `package-install' does.
This populates `package-alist', and so fixes calling
`package-reinstall' as the first thing done after package "quick
init".  (Bug#53527)
