test: use 2048 bit RSA keys

[mmomtchev]

OpenSSL now requires at least 2048
Refs: #44497

Are you planning to update certs and keys in a follow-up PR?

[mmomtchev]

@lpinca Just realized that these were comitted too, done

@lpinca This turned to be much more laborious that I previously thought so I scaled it back to simply replacing all 1024 bit keys with 2048 bit keys, I am leaving the 2048->4096 transition to the next unlucky soul because there is a list of hard-coded test vectors produced with another crypto system meant for testing compatibility.

There is also the DH512 keys which have been blocked (?) because of the logjam attack, I will do them separately

node-test-commit-linuxone-rhel8-s390x is an abort on an out of memory condition - is this a flaky test?
