msmtp: OpenSSL is discouraged, use GnuTLS instead

- removed build option for OpenSSL entirely and always use GnuTLS
  - why OpenSSL is discouraged: https://marlam.de/msmtp/news/openssl-discouraged/
- update IDN to use libdn2, but it is not required anymore since GnuTLS has build-in support for IDN
- disable msmtpd by default
