crypto: drbg - Flatten the DRBG menu

Browse Source 
Now that the menuconfig CRYPTO_DRBG_MENU has no options in it other than
the hidden symbol CRYPTO_DRBG, remove it and move CRYPTO_DRBG to its
parent menu.  Give CRYPTO_DRBG an appropriate prompt and help text.

Enable this only if you need it for a FIPS 140 certification.
It's otherwise redundant with the kernel's regular RNG.
