With older kernels, printf.sh and bitmap.sh fail because they can't find the respective test modules they are looking for. Use modprobe dry run to check for missing test_XXX module. Error out with the same error code as prime_numbers.sh. v3: As pointed out by Kees, modules can be in-built too, so use 'modprobe -q -n' to check presence of the module, instead of 'find ..'. v2: Per Shuah's review, search for the module rather than do modprobe.
