Remove unused macros from config.h.

HAVE_SIGNAL_H, HAVE_TM_GMTOFF, HAVE_TM_ZONE and HAVE_TIMEGM macros are no longer used; so remove them.

HAVE_SYS_TIME_H has been only used in DateMath.cpp, but in other parts of blink we use !OS(WIN) to guard including <sys/time.h>, so lets do the same in DateMath.cpp as well.
