Update gnome-keyring to 2.26.0.

Changes between 2.24.0 and 2.26.0:
==================================

    * Refactor PKI code to make it modular, loosely coupled and easier
      to hack and test.
    * Add standard widgets for display of certificates.
    * If login keyring doesn't exist when changing a PAM password,
      don't create it automatically.
    * Overhaul the secure memory allocator to have memory guards,
      be valgrind compatible, and also be sparing with secure memory.
    * When importing keys, prompt to initialize new PKCS#11 tokens.
    * Fix export of RSA keys to be more interoperable.
    * Make the gp11 library multi-thread safe.
    * Rework initialization of daemon, and the way that it
      integrates with the new session manager.
    * Close open file descriptors before starting daemon from PAM.
    * Don't leave keyring daemon running if PAM just started it
      for a password change.
    * Register environment variables with session properly.
    * Remove usage of deprecated glib/gtk stuff.
    * Hundreds of other smaller changes and fixes.
