rS342984: Add AT_HWCAP / AT_HWCAP2 to elf64_sysvec_v2.

Summary

I was working on implementing ifuncs on powerpc64 elfv2 today, and I suddenly realized that the reason I was having so much trouble with AT_HWCAP and AT_HWCAP2 is they are missing from the sysentvec.

After adding them, the auxv is being filled like it should.
