This uses the `isa-debug-exit` device to pass an exit code to QEMU. By default this device is not available but can be enabled using the `-device isa-debug-exit` switch on the QEMU command-line. Github-Fixes: unikraft#1018 Signed-off-by: Marco Schlumpp <marco@unikraft.io>

Feature request summary
This issue tracks adding a shutdown cause to
system_offin order to properly propagate an error code following a VM EXIT.This is useful in contexts where the returning code is used to determine whether the execution of a unikernel image was successful. For example, in a CI/CD context and a run-to-completion-type unikernel, i.e. one that runs the internal test suite, is executed. If test failures occur, a non-zero error code should be propagated via a return code which will ultimately become visible through the CI/CD software. In Unikraft's case, this is will be shown in incoming PRs.
