Since Buildroot commit [1] "update to Bootlin toolchains 2025.08-1",
the tests.package.test_msr_tools fails when building its Kernel 5.15.55
with gcc 15.1.0.
This commit fixes the issue by updating the test Kernel to the latest
LTS version (6.12.42 at the time of this commit) which includes the
fix for gcc-15. Note: the 5.15.y series does not include this fix for
the x86_64 architecture, which is why this commit switches to 6.12.y.

Add a simple test to verify that msr-tools are working.
The test needs to build a custom x86_64 kernel with support for CPUID and
MSR.
As the TSC_AUX MSR is emulated on qemu we can use it to test that a value
written with wrmsr can indeed be read back with rdmsr.
