Commentary:

If the change is accpted, please consider fixing this for emacs-28.
The reproducer represents a common use-case, e.g. see bug #31397.
Moverover, it is a one-line change unlikely to affect anything aside
this and similar use-cases.

I will submit a patch as soon as I have a BugID from the tracker.
Although this change is rather trivial I need to practice this
process.

Reproducer:

NOTE: Make sure you have a folder beneth your home directory called
"elpa" and that it is empty.

Launch emacs -Q
Insert and evaluate:

(progn
  (setq package-user-dir "~/elpa")
  (setq package-archives
'(("MELPA" .
   "https://melpa.org/packages/")))
  (require 'package)
  (unless (package-installed-p 'use-package)
    (package-install 'use-package)))

Expected result:

 Packages are installed under ~/elpa

Actual Result:

Debugger entered--Lisp error: (void-function package-installed-p)
  (package-installed-p 'use-package)
  (if (package-installed-p 'use-package) nil (package-install 'use-package))
  (progn (if (package-installed-p 'use-package) nil (package-install
'use-package)))
  elisp--eval-last-sexp(nil)
  eval-last-sexp(nil)
  funcall-interactively(eval-last-sexp nil)
  command-execute(eval-last-sexp)

Work-around:

(progn
  (setq package-user-dir "~/elpa")
  (setq package-archives
'(("MELPA" .
   "https://melpa.org/packages/")))
  (require 'package) ;; workaround
  (unless (package-installed-p 'use-package)
    (package-install 'use-package)))
