This line should have been part of the next patch technically, because
it's the version bump of sysdig that requires this Lua 5.1.

I nevertheless wanted to apply, but unfortunately, it fails to build
for me:

I initially tried with Linux 7.3, thought it was too new, so tried
with Linux 6.18, which is the latest LTS. Is that also too new?

Defconfig tested:
