samples/seccomp: fix dependencies on arch macros
This change fixes the compilation error triggered here for i386 allmodconfig in linux-next: http://kisskb.ellerman.id.au/kisskb/buildresult/6123842/ Logic attempting to predict the host architecture has been removed from the Makefile. Instead, the bpf-direct sample should now compile on any architecture, but if the architecture is not supported, it will compile a minimal main() function. This change also ensures the samples are not compiled when there is no seccomp filter support. (Note, I wasn't able to reproduce the error locally, but the existing approach was clearly flawed. This tweak should resolve your issue and avoid other future weirdness.)
