linux: Add AT_SYSINFO_EHDR constant When passed to [`getauxval(3)`][2] this is used to retrieve the base address of the vdso mapped into the current process. It is defined the architecture specific `auxvec.h` headers but [it is defined to the same value in all of them][1] so I've put it in `src/unix/linux_like/linux/mod.rs` instead of in the arch submodule.
