[Buildroot] [git commit branch/2025.02.x] support/testing: test_systemd_selinux: fix test after bootlin toolchains update

[Thomas Perale]

commit: https://git.buildroot.net/buildroot/commit/?id=f54e0595fb3124adaaab77ddff735a7ddab8fbf6
branch: https://git.buildroot.net/buildroot/commit/?id=refs/heads/2025.02.x

Since Buildroot commit [1] "update to Bootlin toolchains 2025.08-1",
the tests.init.test_systemd_selinux fails when building its
Kernel 6.1.26 with gcc 15.1.0.

This commit fixes the issue by updating the test Kernel to the
latest 6.1.y version (6.1.148 at the time of this commit) which
includes several fixes for gcc-15 like this one [2].
