Add the test script for the kernel test driver to analyse vmalloc
allocator for benchmarking and stressing purposes. It is just a kernel
module loader. You can specify and pass different parameters in order
to investigate allocations behaviour. See "usage" output for more
details.
Also add basic vmalloc smoke test to the "run_vmtests" suite.
