crypto: jitterentropy - always select CRYPTO_RNG
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 adds a 'select CRYPTO_RNG' to CRYPTO_JITTERENTROPY to ensure the API is always there when it's used, not just when DRBG is also enabled. CRYPTO_DRBG would set it implicitly through CRYPTO_JITTERENTROPY now, but this leaves it in place to make it explicit what the driver does.

The Jitterentropy RNG is a noise that is intended
to provide seed to another RNG. The RNG does not
