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.

Please note that the patch version details don't belong in the commit log.
I edited it before applying to linux-kselftest next. Please make sure to
add such information in the right place in future patches.
