When running the same kernel in a VM as on the host system and the kernel boot message from the VM appears on the log output, the run tool assumes that the host machine has rebooted unexpectedly. With this commit, an unexpected reboot is assumed only if the kernel boot message appears at the beginning of a line. On base-hw, we enforce a line feed at the beginning of the boot message as the SPIKE emulator log starts with the first message of the kernel lacking a line feed. Fixes #2041
