Makefile: set NO_OPENSSL on macOS by default

Apple removed the OpenSSL header files in macOS 10.11 and above. OpenSSL
was deprecated since macOS 10.7.

Set `NO_OPENSSL` and `APPLE_COMMON_CRYPTO` to `YesPlease` as default for
macOS. It is possible to override this and use OpenSSL by defining
`NO_APPLE_COMMON_CRYPTO`.
