[PATCH] 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.

Changes:
- Move file_stressor.c to filesystems/file_stressor/
- Create filesystems/file_stressor/Makefile for build configuration
- Create filesystems/file_stressor/settings with timeout=1800
- Remove file_stressor from filesystems/Makefile TEST_GEN_PROGS
- Add filesystems/file_stressor to top-level TARGETS in selftests/Makefile
