ci: force reinstall of kernel headers in asan

willcl-ark · willcl-ark · commit 0bd758e6c543 · 2025-07-25T21:59:07.000+01:00
When using hosted runners in combination with cached docker images,
there is the possibility that the host runner image is updated,
rendering the linux-headers package (stored in the cached docker image)
incompatible.

Fix this by doing a re-install of the headers package in
03_test_script.sh.

If the underlying runner kernel has not changed thie has no effect, but
prevents the job from failing if it has.
