PROV: make some DER AID arrays non-static, to avoid clang complaints

The problem encountered is that some arrays were deemed unnecessary by
clang, for example:

    providers/common/der/der_rsa.c:424:28: error: variable 'der_aid_sha224Identifier' is not needed and will not be emitted [-Werror,-Wunneeded-internal-declaration]
    static const unsigned char der_aid_sha224Identifier[] = {
                               ^

However, these arrays are used in sizeof() expressions in other parts
of the code that's actually used, making that warning-turned-error a
practical problem.  We solve this by making the array non-static,
which guarantees that the arrays will be emitted, even though
unnecessarily.  Fortunately, they are very small.
