lib/os: stat_test self-arranges its scratch tree; retire 976_stat_run.c

Browse Source 
Each row builds regfile/symlink/subdir under temp.dir (Hare's os-test
idiom) and asserts exact cleanup, so the suite passes bare and the
carrier's env+tree arrangement job disappears. Every carrier assertion
maps to an in-test row.

/*
* 976_stat_run — execute the lib/os stat fixture under the C-side
* `ww test` driver and assert exit 0.
*
* Workflow (mirrors 975_dirs_run's mkdtemp + exact-cleanup shape):
* 1. mkdtemp /tmp/wwstat-XXXXXX — fresh per run, no parallel-test
* contention.
* 2. Populate the scratch tree:
* <tmp>/regfile regular file, 11 bytes "hello world"
* <tmp>/symlink → ./regfile (relative symlink)
* <tmp>/subdir directory, mode 0700
* 3. setenv WW_TEST_STAT_REGFILE / SYMLINK / SUBDIR / NOENT with
* the absolute paths; lib/os/stat_test.ww reads them via
* os.getenv and exercises stat/lstat/fstat/exists.
* 4. exec `ww test lib/os/stat_test.ww`.
* 5. Remove the exact children and then the mkdtemp-owned root.
*
* Same wrapper shape as 970-975; cleanup runs on success and failure.
