Arnaldo Carvalho de Melo cec07f53c3 perf tools: Move syscall number fallbacks from perf-sys.h to tools/arch/x86/include/asm/
And remove the empty tools/arch/x86/include/asm/unistd_{32,64}.h files
introduced by eae7a755ee ("perf tools, x86: Build perf on older
user-space as well").

This way we get closer to mirroring the kernel for cases where __NR_
can't be found for some include path/_GNU_SOURCE/whatever scenario.
