lib/test_vmalloc.c: allow built-in execution

Browse Source 
Remove the dependency on module loading ("m") for the vmalloc test suite,
enabling it to be built directly into the kernel, so both ("=m") and
("=y") are supported.

Motivation:
- Faster debugging/testing of vmalloc code;
- It allows to configure the test via kernel-boot parameters.

Configuration example:
  test_vmalloc.nr_threads=64
  test_vmalloc.run_test_mask=7
  test_vmalloc.sequential_test_order=1
