The madv_populate selftest has some repetitive code for several different
cases that it covers, included repeated test names used in
ksft_test_result() reports. This causes problems for automation, the test
name is used to both track the test between runs and distinguish between
multiple tests within the same run. Fix this by tweaking the messages
with duplication to be more specific about the contexts they're in.

After commit f7d5bcd35d42 ("selftests: kselftest: Mark functions that
unconditionally call exit() as __noreturn"), ksft_exit_...() functions
are marked as __noreturn, which means the return type should not be
'int' but 'void' because they are not returning anything (and never were
since exit() has always been called).
To facilitate updating the return type of these functions, remove
'return' before the calls to ksft_exit_...(), as __noreturn prevents the
compiler from warning that a caller of the ksft_exit functions does not
return a value because the program will terminate upon calling these
functions.

arm64 does not support the soft-dirty PTE bit. However, the `soft-dirty`
test suite is currently run unconditionally and therefore generates
spurious test failures on arm64. There are also some tests in
`madv_populate` which assume it is supported.
For `soft-dirty` lets disable the whole suite for arm64; it is no longer
built and run_vmtests.sh will skip it if its not present.
For `madv_populate`, we need a runtime mechanism so that the remaining
tests continue to be run. Unfortunately, the only way to determine if the
soft-dirty dirty bit is supported is to write to a page, then see if the
bit is set in /proc/self/pagemap. But the tests that we want to
conditionally execute are testing precicesly this. So if we introduced
this feature check, we could accedentally turn a real failure (on a system
that claims to support soft-dirty) into a skip. So instead, do the check
based on architecture; for arm64, we report that soft-dirty is not
supported.

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.
