perf tools: Confine __get_cpuid() to x86 architecture

The __get_cpuid() test is only valid when compiling for x86.  When
compiling for other architectures like ARM/ARM64 the test fails event if
the functionality is not required.

This patch isolate the build-in feature check to x86 platform, allowing
the compilation and usage of PMUs that use the AUXTRACE infrastructure
on other architectures (i.e ARM CoreSight).
