Subject: [PATCH v2 02/14] selftests/nolibc: add macros to enhance maintainability

The kernel targets share the same kernel make operations, the same
.config file, the same kernel image, add MAKE_KERNEL, KERNEL_CONFIG and
KERNEL_IMAGE for them.

Many targets share the same logging related settings, let's add common
variables RUN_OUT, LOG_OUT and REPORT_RUN_OUT for them.

The qemu run/rerun targets share the same qemu system run command, add
QEMU_SYSTEM_RUN for them.
