Allow the .machine keyring to be linked to the secondary_trusted_keys.
After the link is created, keys contained in the .machine keyring will
automatically be searched when searching secondary_trusted_keys.

v3: Initial version
v4: Unmodified from v3
v5: Rename to machine keyring
v6: Unmodified from v5
