The initial ROMs (program and linker) are already attached to the region map of a forked process and don't need to be obtained again from an external ROM service when the 'Child' class asks for them. For the program image, the local Noux ROM service already returned an invalid dataspace capability, but not for the linker. Instead of adding another 'magic' ROM name for the local ROM service, this commit implements an 'empty' ROM service, which returns an invalid dataspace for the initial ROMs. Fixes #2272

* The initial ROMs (binary and linker) are already attached in a forked

|
|
