* debian/control (Build-Depends): Depend on debhelper 8.9.7 for using
  "override-*-arch" and "override-*-indep" targets in debian/rules.
* debian/rules: Completely rewritten to use features from debhelper v7.
* plugins.d/mandos-client.c (fprintf_plus): Cast return value to
  return type; this fixes a warning since TEMP_FAILURE_RETRY seems to
  return a long int, not whatever type its inner expresson returns.
* plugins.d/password-prompt.c (fprintf_plus): - '' -
