runtime: allocate more stack space in CgoCallbackGC test

Allocate enough stack space so that the test will work on a system
    that does not support split stacks.
    
    This test is actually not very meaningful for gccgo at present, but it
    doesn't hurt to keep running it.
    
    Updates golang/go#20931
