The test_string module can't be removed because it lacks an exit hook.
Since there is no reason for it to be permanent, add an empty one to allow
module removal.

Make sure that the trailing NUL is considered part of the string and can
be found.

If a memsetXX implementation is completely broken and fails in the first
iteration, when i, j, and k are all zero, the failure is masked as zero
is returned. Failing in the first iteration is perhaps the most likely
failure, so this makes the tests pretty much useless. Avoid the
situation by always setting a random unused bit in the result on
failure.

Extract the string test code into its own source file, to allow
compiling it either to a loadable module, or built into the kernel.
