fips: Prohibit SHA1 in DH & ECDH exchange

fips: Prohibit SHA1 in DH & ECDH exchange

See Section 5 Key Agreement Using Diffie-Hellman and MQV of
[NIST SP 800-131Ar2](https://nvlpubs.nist.gov/nistpubs/SpecialPublications/NIST.SP.800-131Ar2.pdf).

Strengths less than 112bits is disallowed, thus eliminating SHA1.

Skip cms test case that requires use of SHA1 with X9.42 DH.

Rename ossl_fips_ind_digest_check to ossl_fips_ind_digest_exch_check
