MFC: r229809: Don't include <sys/timeb.h>.
The purpose of not including <sys/timeb.h> is to avoid the compiler
warning we put in <sys/timeb.h>. So this change will cause CVS to
provide its own definition of 'struct timeb'. This is only OK
because the code never calls the libc ftime(3) interface. CVS only
uses 'struct timeb' as a convenience structure -- thus it doesn't
matter how its supplied definition does or does not match the
ftime(3) ABI.
