The `vendor-reset` Linux kernel module stopped building as of kernel
versions 6.8.1 because `strlcopy` has been removed. An upstream patch
fixed this by replacing the only callsite with `strscpy` [^1].
As the patch has already been merged into `master`, I updated the
nix package to the latest trunk commit and labeled the version
as `unstable-2024-04-16`.
Since the only patch specified in the package has already been
merged in late 2022 [^2], we can remove that one as well.
