src,build: add --openssl-default-cipher-list

This commit adds a configuration option named
openssl-default-cipher-list which takes a colon separated string
specifying ciphers that should be used as the default ciphers instead of
the ones defined in node_constants.

The motivation for this is a use case where Fedora/RHEL would like
to be able to specify a default cipher in the format PROFILE=SYSTEM.
This would enable Fedora/RHEL to have a system wide security level for
all applications.
