What were you trying to do that didn't work?

teardown() tries to cleanup /proc dir and cannot exit normally when misses required tool.

I proposed a pr in upstream: https://github.com/xdp-project/xdp-tools/pull/516

It is timeout when missing pkgs in our test on aws (test_xdp_tools_run_tests),

What is the impact of this issue to you?

The command cannot exit when missing dependency.

Please provide the package NVR for which the bug is seen:

xdp-tools-1.5.5-1.el10.x86_64

How reproducible is this bug?:

Steps to reproduce

1. yum install -y xdp-tools wireshark-cli tcpdump nmap-ncat
2. /usr/share/xdp-tools/run_tests.sh

Expected results

Actual results

command got stuck at cleanup "/proc"
