Add new tests to check the correctness of the `-overcommit memlock`
option (possible values: off, on, on-fault) by using
`/proc/{qemu_pid}/smaps` file to check in Size, Rss and Locked fields of
anonymous segments:
* if `memlock=off`, then Locked = 0 on every anonymous smaps;
* if `memlock=on`, then Size, Rss and Locked values must be equal for
every anon smaps where Rss is not 0;
* if `memlock=on-fault`, then Rss and Locked must be equal on every anon
smaps and anonymous segment with Rss < Size must exists.

v5 -> v6:
* add python3 shebang to tests/functional/test_memlock.py
v4 -> v5:
* refactor skipLockedMemoryTest decorator: using resource.getrlimit()
function instead of spawning a process
v3 -> v4:
* add skipLockedMemoryTest decorator to skip test if system's locked
memory limit is below the required threashold;
* add to MemlockTest skipLockedMemoryTest decorator with 2 GB limit.
v2 -> v3:
Move tests to tests/functional dir, as the tests/avocado dir is being phased
out.
v2 was [PATCH v2] tests/avocado: add memlock tests.
Supersedes: <20250414075702.9248-1-dtalexund...@yandex-team.ru>
v1 -> v2:
In the previous send, i forgot to specify new patch version (v2)
So i resend previous patch with version specified.

Gentle ping :)
Also add reviewers from get_maintainer.pl (forget to fix it after
