Use cpu_ticks() for get_cyclecount(9) rather than checking existence of TSC
at run-time on i386.  cpu_ticks() is set to use RDTSC early enough on i386
where it is available.  Otherwise, cpu_ticks() is driven by the current
timecounter hardware as binuptime(9) does.  This also avoids unnecessary
namespace pollution from <machine/cputypes.h>.
