selftests/vm: rename selftests/vm to selftests/mm

Rename selftets/vm to selftests/mm for being more consistent with the
code, documentation, and tools directories, and won't be confused with
virtual machines.

-# In other words, "make userfaultfd" is supposed to fail to build at all,

-# However,  the built-in rules, if not suppressed, will pick up CFLAGS and the

-# set for the full path target!). This causes it to get pretty far into building
