Subject: [PATCH 5.4] selftests/bpf: fix goto cleanup label not defined

kernel test robot found a warning when build bpf selftest for 5.4.y stable
tree:

prog_tests/stacktrace_build_id_nmi.c:55:3: error: label ‘cleanup’ used but not defined
   goto cleanup;
   ^~~~

This is because we are lacking upstream commit dde53c1b763b
("selftests/bpf: Convert few more selftest to skeletons"). But this
commit is too large and need more backports. To fix it, the
easiest way is just use the current goto label 'close_prog'.

Reported-by: kernel test robot <rong.a.chen@...el.com>
Fixes: da43712a7262 ("selftests/bpf: Skip perf hw events test if the setup disabled it")
