ci: qemu sometimes segfaults when build testing other archs

@JustSoup321 noticed this in a recent CI run (build-aarch64), the runner was ci-x64-runner3-docker-postmarketos (x86_64 CPU):

>>> device-pine64-pinephonepro: Analyzing dependencies...
qemu-aarch64-static: QEMU internal SIGSEGV {code=128, addr=0}
Segmentation fault (core dumped)
< that repeats a few more times ... >
qemu: uncaught target signal 11 (Segmentation fault) - core dumped
Segmentation fault (core dumped)
>>> ERROR: device-pine64-pinephonepro: builddeps failed

Important

If you noticed this failure, please comment below with the runner! The runner name is usually visible on the right side of the CI job page, or at the top of the CI job output, like:

Running with gitlab-runner 17.5.2 (c6eae8d7)
  on 5: ci-x64-runner3-docker-postmarketos hnB2RHmXb, system ID: s_5433359204a5
...

Knowing whether or not this happens on specific runners could be helpful for identifying the problem.
