The new gcc version 14 now complains when calloc is called
with inverted arguments:

	../benchmarks/gem_exec_reloc.c:85:31: warning: ‘calloc’ sizes specified with ‘sizeof’ in the earlier argument and not in the later argument [-Wcalloc-transposed-args]
	   85 |         target = calloc(sizeof(*target), num_relocs);
	      |                               ^
	../benchmarks/gem_exec_reloc.c:85:31: note: earlier argument should specify number of elements, later size of each element

Replace all occurrences of calloc that were warned on gcc 14 by
placing the arguments at the right order.

Logic fixed using this small python script, written specifically
to catch gcc calloc warnings:
