kunit: qemu_configs: SH: Respect kunit cmdline

The default SH kunit configuration sets CONFIG_CMDLINE_OVERWRITE which
completely disregards the cmdline passed from the bootloader/QEMU in favor
of the builtin CONFIG_CMDLINE.
However the kunit tool needs to pass arguments to the in-kernel kunit core,
for filters and other runtime parameters.

Enable CONFIG_CMDLINE_EXTEND instead, so kunit arguments are respected.
