crypto: acomp - search acomp with scomp backend in crypto_has_acomp



users may call crypto_has_acomp to confirm the existence of acomp before using
crypto_acomp APIs. Right now, many acomp have scomp backend, for example, lz4,
lzo, deflate etc. crypto_has_acomp will return false for them even though they
support acomp APIs.
