Don't define the AT_RENAME_* macros when __USE_GNU is defined since
/usr/include/stdio.h defines them in that case (i.e. when _GNU_SOURCE
is defined, which causes __USE_GNU to be defined).
Having them defined in 2 places causes build warnings (duplicate
definitions) in both samples/watch_queue/watch_test.c and
samples/vfs/test-statx.c.
Fixes: b4fef22c2fb9 ("uapi: explain how per-syscall AT_* flags should be allocated")
