kmod-v4l2loopback differs between builds, e.g. on apm821xx/nand, as
v4l2loopback.ko carries the absolute path of the kernel tree:
/builder/shared-workdir/build/build_dir/.../linux-6.18.52/include/linux/ucopysize.h
The module is built by calling make -C $(LINUX_DIR) directly, so none
of the OpenWrt prefix maps apply, and since Linux 6.13 kbuild includes
the kernel headers of external modules by their absolute path.
Build through $(KERNEL_MAKE), which passes KERNEL_MAKE_FLAGS and with
them the prefix maps of the build and staging directories, like the
kernel packages of the main repository do. ARCH and CROSS_COMPILE come
with KERNEL_MAKE_FLAGS as well.

With the recent move to using ZSTD as the default compression format
for packaging git repo clones we must refresh all of the hashes for
the packages feed as well.
