[PATCH v2 1/2] selftests/filesystems: Move file_stressor to dedicated subdirectory

[Disha Goel]

The file_stressor test requires a 30-minute timeout (1800 seconds) due to
its 15-minute runtime plus setup/teardown overhead. This is significantly
longer than the default 45-second timeout used by other filesystem tests.

Move file_stressor into its own subdirectory (filesystems/file_stressor/)
with a dedicated settings file to isolate its timeout configuration. This
prevents the long timeout from affecting other fast-running tests in the
filesystems/ directory.

This restructuring follows the pattern used by other selftests with special
requirements and ensures proper timeout handling in CI/CD environments
while maintaining the default 45-second timeout for other filesystem tests.
