Stop using EVP_MD_CTX_FLAG_NON_FIPS_ALLOW
This is a flag that has lost its relevance. The new mechanism to do
the same thing is to fetch the needed digest explicitly with "-fips"
as property query, i.e. we remove any requirement for that property to
be set when fetching, even if the default property query string
requires its presence.
