[PATCH 4/6] DRBG: Select correct DRBG core for stdrng

[Stephan Mueller <smueller@chronox.de>]

When the DRBG is initialized, the core is looked up using the DRBG name.
The name that can be used for the lookup is registered in
cra_driver_name. The cra_name value contains stdrng.

Thus, the lookup code must use crypto_tfm_alg_driver_name to obtain the
precise DRBG name and select the correct DRBG.
