Subject: [PATCH v3 4/5] tools/testing/selftests/sysctl/sysctl.sh: support CONFIG_TEST_SYSCTL=y

The testing script recommends CONFIG_TEST_SYSCTL=y, but actually only works
with CONFIG_TEST_SYSCTL=m. Testing of sysctl setting via boot param however
requires the test to be built-in, so make sure the test script supports it.
