Comment (by mojca@…):

 I needed `p5.20-crypt-passwdmd5` due to an upgrade of `p5-fusioninventory-
 agent` (#46443) and made unauthorized commits r131157 & r131158. Unless
 you plan to roll back for some reason, the only patch left is to remove
 the last part with `iconv` and the `post-patch` "hack".
