settings: don't hard-code HTTPS capability This partially reverts bdec62dce1c17465b7330100ea2f71e63fc411dd which activates the transport code-paths which allow you to use a custom TLS implementation without having to have one at build-time. However the capabilities describe how libgit2 was built, not what it could potentially support, bring back the ifdefs so we only say we support HTTPS if libgit2 was itself built with a TLS implementation.
