restore attribute((const)) to pthread_self and errno location decls

revert commit a603a75a72bb469c6be4963ed1b55fabe675fe15. as a result of commit 1c84c99913bf1cd47b866ed31e665848a0da84a2 this is now safe, assuming an interpretation of the somewhat-underspecified attribute((const)) consistent with real-world usage.
