Since Buildroot commit [1] "update to Bootlin toolchains 2025.08-1",
the tests.package.test_dpdk fails to build its Kernel 6.6.58 with
gcc 15.1.0.
This commit fixes the issue by updating the test Kernel version to
the latest 6.6.y version (6.6.102 at the time of this commit) which
includes the fix for gcc-15.
