This should be sys_mm_swap01; otherwise, the runtest file cannot
find the correct test to execute.

I suggest adding all of those path definitions to tst_path_defs.h
and unifying the common macro names.


Also, we need to add the sysfs/ directory to testcases/kernel/Makefile
so they can build successfully by default.
