[LTP] [PATCH v1] Add rename15 test

Andrea Cervesato
2024-01-19T09:23:31Z

From: Andrea Cervesato <andrea.cervesato@suse.com>

This test has been extracted from symlink01 and it verifies that
rename() is working correctly on symlink() generated files, renaming
symbolic link and checking if stat() information are preserved.
