uhd: Moved get_system_time outside of public API
uhd::get_system_time() is an abstracted way of reading back a time, and is not UHD-specific. As such, there's no reason to keep it in the public part of the API where we're contractually obligated not to touch it. Instead, moving it to the internal API space.
