users may call crypto_has_acomp to confirm the existence of acomp before using
crypto_acomp APIs. Right now, many of acomp have scomp backend, for example,
lz4, lzo, deflate etc. crypto_has_acomp will return false for them even though
they support acomp APIs.
One possible way to make has_acomp true for them is calling this APIs like
crypto_has_acomp("xxx", CRYPTO_ALG_TYPE_SCOMPRESS, 0);
But it looks quite weird.
