lib/crypto: tests: Add a .kunitconfig file

Add a .kunitconfig file to the lib/crypto/ directory so that the crypto
library tests can be run more easily using kunit.py.  Example with UML:

    tools/testing/kunit/kunit.py run --kunitconfig=lib/crypto

Example with QEMU:

    tools/testing/kunit/kunit.py run --kunitconfig=lib/crypto --arch=arm64 --make_options LLVM=1
