This commit fixes the following failures in OpenSSL FIPS using the
`OPENSSL_FORCE_FIPS_MODE=1` in CentOS stream 9 non-FIPS OS environment.

make: *** [uncommon.mk:1249: runruby] Error 2
```
Note that we obverved the issue in RHEL 9.4 Beta non-FIPS OS environment too.
The error happened by applying the patch
ruby-3.3.0-openssl-3.2.0-fips-fix-pkey-read-in-openssl-3.patch
rewriting the `ossl_pkey_read_generic` properly.
The error didn't happen without the patch.
