support/testing: add test for msr-tools

Browse Source 
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.
