Enable host-clock-based RTC
Switch RTC emulations to the new host_clock instead of vm_clock by default. This has the advantage that the emulated RTC will follow automatically the host time while it might be tuned via NTP. vm_clock can still be selected by passing '-rtc clock=vm' on the command line. Note that some RTC emulations (at least M48T59) already use the host time unconditionally while others (namely MC146818) do not. This patch introduces the required infrastructure for selecting the base clock but only converts MC146818 for now.
