Fixing ssl-cert-{sha512,sha256,sha1,md5}()

These functions are generated in a loop. However, the way they were
generated was broken. The loop variable is *not* replaced by a literal
string in the resulting functions. Therefore, as soon as the variable
is unset all functions become broken. Luckily, they broke loudly.
Otherwise this may not have been caught easily.
