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.
