virt: sevguest: Add CONFIG_CRYPTO dependency

This driver fails to link when CRYPTO is disabled, or in a loadable
module:

  WARNING: unmet direct dependencies detected for CRYPTO_GCM
  WARNING: unmet direct dependencies detected for CRYPTO_AEAD2
    Depends on [m]: CRYPTO [=m]
    Selected by [y]:
    - SEV_GUEST [=y] && VIRT_DRIVERS [=y] && AMD_MEM_ENCRYPT [=y]

x86_64-linux-ld: crypto/aead.o: in function `crypto_register_aeads':
