Log:
[ruby/openssl] test_pkey_rsa.rb: Fix test_private_encoding_encrypted in OpenSSL 4.0 FIPS

OpenSSL 4.0.0 added a check for Password-Based Key Derivation Function 2
(PBKDF2) to require the minimal password length 8 in FIPS by the following
commit.
https://github.com/openssl/openssl/commit/71ed0fc8b3cdb33cd06059416686f8972ede0248

This commit fixes the following test failure in OpenSSL 4.0 FIPS by changing
testing password length from 6 to 8..

```
