[test] [linux] define PR_SET_PTRACER constants if the system does not provide them 

Android API <= 16 header do not have these symbols defined, but the kernel does support the
relevant calls. And in general, since these calls are on a best-effort basis, it won't hurt even
if we try to run in on a really ancient kernel.
