REGTESTS: ssl: add a PEM with mix of LF and CRLF line endings

User tried to update a PEM, generated automatically. Part of this PEM has LF
line endings, and another part (CA certificate), added by some API, has CRLF
line endings. This has revealed a bug in cli_snd_buf(), see more
details in issue GitHUB #2818. So, let's add an example of such PEM in our
SSL regtest.
