Following commits improved test results:

8040100201 Fix error reporting (false negatives) in SGID tests
Improved SGID test handling by unifying error reporting and using secure temporary directories.
Replaced non-standard exit codes and fixed premature exits to avoid masking failures.
These changes reduced false negatives, increasing overall test pass rates.

8624f6431b elf: Fix subprocess status handling for tst-dlopen-sgid (bug 32987)
Fixed tst-dlopen-sgid false positives by correctly handling subprocess exit status (bug 32987).
Ensured test fails on abnormal or non-zero child exits.
This commit restores reliability in SGID testing and is the first step toward centralized SGID test error handling.
