Subject: [PATCH] samples/bpf: exit with tracex7's status in
 test_override_return.sh

The script checks $? of ./tracex7 correctly, but the else branch only echoes
FAILED! - it does not remember the status.  The script's last command is
'losetup -d $DEVICE', so the exit status is losetup's (0 on success) and a run whose
test failed still reports success.

Save $? into rc, use it for the decision, and exit with it after the losetup cleanup
(the cleanup still runs).

The file is byte-identical to upstream v6.6.119, so this is a drive-by fix of an
upstream wart rather than a regression of this tree.
