lib/test_vmalloc.c: allow built-in execution
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
