test suite: use a RSA certificate rather than ECDSA.

It's arguably the most common use-case.  Generated with

  $ openssl genpkey -algorithm RSA -out tests/snippets/dovecot/dovecot.rsa.key
  $ openssl req -x509 -days 3650 -subj "/CN=InterIMAP test suite" \
        -key tests/snippets/dovecot/dovecot.rsa.key \
        -out tests/snippets/dovecot/dovecot.rsa.crt
