tools: fix ARRAY_SIZE defines in tools and selftests hdrs
tools/include/linux/kernel.h and kselftest_harness.h are missing ifndef guard around ARRAY_SIZE define. Fix them to avoid duplicate define errors during compile when another file defines it. This problem was found when compiling selftests that include a header with ARRAY_SIZE define. ARRAY_SIZE is defined in several selftests. There are about 25+ duplicate defines in various selftests source and header files. Add ARRAY_SIZE to kselftest.h in preparation for removing duplicate ARRAY_SIZE defines from individual test files.
