msmtp: update to version 1.8.7

- It brings oauthbearer support
- It switches from OpenSSL to GnuTLS, which is fully compatible and
  brings more parameters

Makefile changes:
- Fix SPDX License Identifier
- Add PKG_CPE_ID
- The Project does not use sourceforce anymore.
- Uses GnuTLS instead of OpenSSL, which was discouraged
