Add VxWorks fixincludes hack, #include sysLib.h in time.h

Make sure there is a visible prototype of sysClkRateGet() when
CLOCKS_PER_SEC is #defined to that in time.h for VxWorks.  This
would typically be provided by sysLib.h.

2021-01-10  Olivier Hainque  <hainque@adacore.com>

	* inclhack.def (vxworks_time_h_syslib): New hack.
	* tests/base/time.h: Update.
	* fixincl.x: Regenerate.
