mutually exclusive but can both be used on the same command line.

This commit adds a check if both options are used.

Currently, the following warning will be reported when configuring
without-ssl:

../src/node.cc:3653:8: warning: unused variable 'use_bundled_ca'
[-Wunused-variable]
  bool use_bundled_ca = false;
       ^
../src/node.cc:3654:8: warning: unused variable 'use_openssl_ca'
[-Wunused-variable]
  bool use_openssl_ca = false;
       ^

I missed this when working on
commit 8a7db9d ("src: add
--use-bundled-ca --use-openssl-ca check").
