Log:
  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.
