Fix test_ssl.rb in FIPS.

test_post_connect_check_with_anon_ciphers:
test_tmp_dh_callback:
test_tmp_dh:

DH missing the q value on unknown named parameters (ciphers) is not
FIPS-approved, according to the FIPS-186-4 APPENDIX B: Key Pair Generation -
B.1.1 Key Pair Generation Using Extra Random Bits, the inputs p, q, and g are
required. However, TLS doesn't send q.
https://csrc.nist.gov/pubs/fips/186-4/final

OpenSSL has a special workaround to recover the missing "q" value for known
named parameters, which is the reason why other tests that use the default
parameters in `lib/openssl/ssl.rb` are working.

Note that the test_post_connect_check_with_anon_ciphers test got the following error on
`OpenSSL.debug = true` in FIPS.

```
/home/jaruga/var/git/ruby/openssl/lib/openssl/ssl.rb:551: warning: error on stack: error:0A0C0103:SSL routines:tls_construct_server_key_exchange:internal error
```

test_get_ephemeral_key:

kRSA (PKCS1-v1_5 padding) is not allowed in FIPS according to the
NIST SP 800-131A Rev. 2 - 6 Key Agreement and Key Transport Using RSA -
Table 5: Approval Status for the RSA-based Key Agreement and Key Transport
Schemes - PKCS1-v1_5 padding - Disallowed after 2023
https://csrc.nist.gov/pubs/sp/800/131/a/r2/final

Note that the test_get_ephemeral_key test got the following error on
`OpenSSL.debug = true` in FIPS.

```
test/openssl/test_ssl.rb:2326: warning: error on stack: error:1C8000A8:Provider routines:rsa_encrypt:invalid padding mode
```
