Subject: [PATCH] selftests: resctrl: ignore builds for unsupported architectures

This test doesn't have support for other architectures. Altough resctrl
is supported on x86 and ARM, but arch_supports_noncont_cat() shows that
only x86 for AMD and Intel are supported by the test. We get build
errors when built for ARM and ARM64.

Hence add support in the Makefile to build this suite only for x86 and
x86_64 architectures.

Fixes: b733143cc455 ("selftests/resctrl: Make resctrl_tests run using kselftest framework")
