[HIPIFY] hipify-perl produces incorrect output for kernels that have no input args

[mattsinc]

I am porting an application that exclusively uses hipMemcpyToSymbol for its kernels. When I run hipify-perl on this, it will happily convert it (except for the threadfence issue I noted in #32). However, when I try to compile the kernel I get the following for each kernel:

hipLaunchKernelGGL((Kernel1), dim3(numTBs), dim3(numThreadsPerBlock), 0, 0, );

This is related to the issue I raised in ROCm/HIP#257 -- currently hipcc requires at least one input arg to correctly compile a kernel, when this is not necessary if MemcpyToSymbol is used. But regardless, it doesn't seem like hipify should add a comma with nothing after it.
