crypto: vmx - add missing dependencies

Browse Source 
vmx-crypto module depends on CRYPTO_AES, CRYPTO_CBC, CRYPTO_CTR or
CRYPTO_XTS, thus add them.

These dependencies are likely to be enabled, but if
CRYPTO_DEV_VMX=y && !CRYPTO_MANAGER_DISABLE_TESTS
and either of CRYPTO_AES, CRYPTO_CBC, CRYPTO_CTR or CRYPTO_XTS is built
as module or disabled, alg_test() from crypto/testmgr.c complains during
boot about failing to allocate the generic fallback implementations
(2 == ENOENT):
