kcsan: test: Add a .kunitconfig to run KCSAN tests 



Add a .kunitconfig file, which provides a default, working config for
running the KCSAN tests. Note that it needs to run on an SMP machine, so
to run under kunit_tool, the --qemu_args option should be used (on a
supported architecture, like x86_64). For example:
./tools/testing/kunit/kunit.py run --arch=x86_64 --qemu_args='-smp 8'
					--kunitconfig=kernel/kcsan

# Note that the KCSAN tests need to run on an SMP setup.

# Under kunit_tool, this can be done by using the --qemu_args

# option to configure a machine with several cores. For example:

# ./tools/testing/kunit/kunit.py run --kunitconfig=kernel/kcsan \

# 				 --arch=x86_64 --qemu_args="-smp 8"

# This prevents the test from timing out on many setups. Feel free to remove

# (or alter) this, in conjunction with setting a different test timeout with,

# for example, the --timeout kunit_tool option.
