corrected offline kernel compilation on hipcc path

1. hipgenisa.sh now adds int main(){} during kernel compilation. User does not have to put it there
2. Renamed vcpy_isa.cpp to vcpy_kernel.cpp
3. Removed vcpy_isa.cu as the kernel code should be common for both paths
4. Changed Makefile and runkernel.cpp to work with above changes
