Add a secondary system keyring that can be added to by root whilst the system is running - provided the key being added is vouched for by a key built into the kernel or already added to the secondary keyring. Rename .system_keyring to .builtin_trusted_keys to distinguish it more obviously from the new keyring (called .secondary_trusted_keys). The new keyring needs to be enabled with CONFIG_SECONDARY_TRUSTED_KEYRING. If the secondary keyring is enabled, a link is created from that to .builtin_trusted_keys so that the the latter will automatically be searched too if the secondary keyring is searched.
