selftests/mm: make migration test robust to failure
The `migration` test currently has a number of robustness problems that
cause it to hang and leak resources.
Timeout: There are 3 tests, which each previously ran for 60 seconds.
However, the timeout in mm/settings for a single test binary was set to 45
seconds. So when run using run_kselftest.sh, the top level timeout would
trigger before the test binary was finished. Solve this by meeting in the
middle; each of the 3 tests now runs for 20 seconds (for a total of 60),
and the top level timeout is set to 90 seconds.
Leaking child processes: the `shared_anon` test fork()s some children but
then an ASSERT() fires before the test kills those children. The assert
causes immediate exit of the parent and leaking of the children.
Furthermore, if run using the run_kselftest.sh wrapper, the wrapper would
get stuck waiting for those children to exit, which never happens. Solve
this by setting the "parent death signal" to SIGHUP in the child, so that
the child is killed automatically if the parent dies.
With these changes, the test binary now runs to completion on arm64, with
2 tests passing and the `shared_anon` test failing.

selftests/mm: fix unused variable warnings in hugetlb-madvise.c, migration.c
Dummy variables are required in order to make these two (similar)
routines work, so in both cases, declare the variables as volatile in
order to avoid the clang compiler warning.
Furthermore, in order to ensure that each test actually does what is
intended, add an asm volatile invocation (thanks to David Hildenbrand
for the suggestion), with a clarifying comment so that it survives
future maintenance.
