KEYS: Make the system trusted keyring depend on the asymmetric key type
Make the system trusted keyring depend on the asymmetric key type as there's not a lot of point having it if you can't then load asymmetric keys onto it. This requires the ASYMMETRIC_KEY_TYPE to be made a bool, not a tristate, as the Kconfig language doesn't then correctly force ASYMMETRIC_KEY_TYPE to 'y' rather than 'm' if SYSTEM_TRUSTED_KEYRING is 'y'. Making SYSTEM_TRUSTED_KEYRING *select* ASYMMETRIC_KEY_TYPE instead doesn't work as the Kconfig interpreter then wrongly complains about dependency loops.
