When building the jitterentropy driver by itself, we get a link error
when CRYPTO_RNG is not enabled as well:
crypto/built-in.o: In function `jent_mod_init':
jitterentropy-kcapi.c:(.init.text+0x98): undefined reference to
`crypto_register_rng'
crypto/built-in.o: In function `jent_mod_exit':
jitterentropy-kcapi.c:(.exit.text+0x60): undefined reference to
`crypto_unregister_rng'
This moves the 'select CRYPTO_RNG' from CRYPTO_DRBG to CRYPTO_JITTERENTROPY
to ensure the API is always there when it's used, not just when DRBG is
also enabled.
