[PATCH v2 02/10] crypto: add algorithm type specific flag, CRYPTO_ALG_PRIVATE

In following patch, new synchronous compression APIs will be
introduced and it needs one flags to determine whether context buffer is
needed or not for decompression. It can be implemented by flag in it's own
algorithm structure definition but because there is a room in general
crypto_alg flag, this patch reuses it to reduce complexity. It possibly
can be used for other algorithm type.
