This patch modifies igt_runner to support runner_kmemleak() calls. By
default, kmemleak scanning is disabled, so new command-line options are
introduced to enable it:
 * -k, -k<option>, --kmemleak, --kmemleak=<option>

The available options are:
 * once: Do single kmemleak scan after last test in the test list
 * each: Perform a kmemleak scan after each test completes

By default, kmemleak scanning is disabled. If any kmemleaks are
detected, they will be saved in the igt_runner results directory under
kmemleak.txt.

Additionally, this patch updates serialize_settings() and
read_settings_from_file() to persist igt_runner settings across runs.
This allows settings to be saved when running igt_runner --dry-run and
later restored when executing igt_resume.

The unit tests for igt_runner have been extended to verify:
 * Kmemleak scans are disabled by default
 * Kmemleak scans can be enabled via command-line arguments
 * The kmemleak setting is correctly saved to and restored from disk

To test the new -k command-line option, this patch appends "--overwrite"
to *argv[] in runner_test.c to expand the argument array. This approach
avoids a major refactor of how *argv[] is defined across the file while
keeping the changes isolated to unit testing. Since this only affects
tests, there is no downstream impact.
