bug#38473: 27.0.50; package-install of package with unversioned Package-Requires fails due to unsatisfiable requirements

[Alex Bennée]

I originally triggered this bug while trying to upgrade packages from
MELPA however I can replicate by browsing to the file lusty-explorer
from the repo and executing M-x package-install-file. According to the
docs the line:

  ;; Package-Requires: (cl-lib dired)

is valid and the version should be defined as 0 - however this somehow
gets converted into trying to install dired-0. The following is the
relevant dumps from my logs:
