tool build: Remove __get_cpuid feature test

Browse Source 
This feature test is no longer used so remove.

The function tested by the feature test is used in:
tools/power/x86/x86_energy_perf_policy/x86_energy_perf_policy.c
however, the Makefile just assumes the presence of the function and
doesn't perform a build feature test for it.
