Deleted Safeclib files and created symbolic link safeclib instead (#5651) 

* made a new symbolic link for safeclib and deleted safeclib files. Currently WIP

* added safeclib path to OBJS paths. Columnar successfully builds but Citus build still fails

* DESCRIPTION
* This function copies at most smax bytes from src to dest, up to

*
* src pointer to the memory that will be copied to dest
*
* smax maximum number bytes of src to copy
*
* OUTPUT PARAMETERS
* dest is updated

* RUNTIME CONSTRAINTS
* Neither dest nor src shall be a null pointer.
* Neither dmax nor smax shall be zero.
* dmax shall not be greater than RSIZE_MAX_MEM.
* smax shall not be greater than dmax.
* Copying shall not take place between regions that overlap.
* If there is a runtime-constraint violation, the memcpy_s function
