Update to 0.6.40

Required for gnome-control-center 3.16 (bug 1466245)

This bug was fixed in the package accountsservice - 0.6.40-2ubuntu1

---------------
accountsservice (0.6.40-2ubuntu1) wily; urgency=medium

  * Merge with Debian, remaining Ubuntu changes (LP: #1466289):
  * debian/compat:
    - Use version 9.
  * debian/control:
    - Use debhelper version 9.
    - Add libpam-pin build-depends: dh-exec, libgcr-3-dev, libgcrypt11-dev,
      libgnutls-dev, libpam0g-dev.
    - Use multi-arch.
    - libaccountsservice-dev depends on gir1.2-accountsservice-1.0, not
      libgirepository1.0-dev.
    - Add libpam-pin package.
  * debian/rules:
    - Use -O1 instead of -O2 because it works around a problem with
      the manager object never reporting its readiness to users of
