base-passwd: Update to 3.5.52

* Add a patch to allow the use of debconf to be disabled.
* Replace 0007-Disable-generation-of-the-documentation.patch with a new
  patch to disable the generation of the documentation using a
  configuration option.
* Replace 0006-Disable-shell-for-default-users.patch with a sed
  expression that uses a variable, NOLOGIN, to specify what command to
  use for users that are not expected to login. This allows to use some
  other command than "nologin", e.g., "false". Also, by using
  ${base_sbindir}, it adheres to usrmerge being configured.
