uml: fix compile for x86-64

Randy Dunlap reports that we get arch/x86/um/shared/sysdep/ptrace.h:7:20: error: redefinition of 'regs_return_value' arch/x86/um/shared/sysdep/ptrace.h:7:20: note: previous definition of 'regs_return_value' was here when compiling UML for x86-64. Stephen Rothwell root-caused it and says: "Caused by commit d7e7528 ("Audit: push audit success and retcode into arch ptrace.h") (another patch that was never in linux-next :-(). This file now needs protection against double inclusion." so let's do as the man says.
