Ensure the we pass the correct symbol address to objcopy

Browse Source 
If kernel.Kmain defines a nested function then a symbol like `github.com/achilleasa/gopher-os/kernel.Kmain.func1` will be generated. To make sure we always pick the `github.com/achilleasa/gopher-os/kernel.Kmain` symbol address we just need to add a `$` to the grep argument.
