cmake: Implement support of GNOME Keyring authentication trough libsecret

library.

- for finding the libsecret library we are going to use pkgconfig modules of
  it trough FindPkgConfig CMake module [1].

* build/generator/gen_cmake.py
  (get_target_conditions): Use SVN_ENABLE_AUTH_GNOME_KEYRING condition
   variable for the libsvn_auth_gnome_keyring library.
  (check_ignore_target): Remove libsvn_auth_gnome_keyring from ignore_names.
* CMakeLists.txt
  (options): Define SVN_ENABLE_AUTH_GNOME_KEYRING option.
  (GNOME Keyring): Search for libsecret using pkgconfig, create interface
   library for this dependency, define SVN_HAVE_LIBSECRET definition.
  (configure summary): Write state of SVN_ENABLE_AUTH_GNOME_KEYRING.
