Segfault when linked with libbpf-sys version 1.5.0

[abrehman94]

When a rust scx scheduler is built with libbpf-sys version 1.5.0+v1.5.0 it causes a seg fault.

17:38:01 [INFO] scx_flash 1.0.7-gfa1e12a-dirty x86_64-unknown-linux-gnu/debug SMT off

./clean_build.sh: line 6: 96847 Segmentation fault      sudo ./target/debug/scx_flash

As far as I could identify, the previous version that works is 1.4.6.

libbpf-rs = "=0.24.8"
libbpf-sys = "=1.4.6"

HI Abdul, did you happen to look more closely into why this is happening?

Hi Emil, no I didn't, as far as I saw was the difference on git in v1.4.6 and v1.5.0 of the libbpfsys - couldn't spot anything that would catch my eye.
