    qca-ossl: Fix build without support for SHA-0
    
    LibreSSL >= 2.3.0 removed support for SHA-0, so there's no EVP_sha
    anymore.
    Wikipedia says about SHA-0: "160-bit hash function published in 1993
    under the name SHA. It was withdrawn shortly after publication due to
    an undisclosed "significant flaw" and replaced by the slightly revised
    version SHA-1.'
