Use uint64_t here. The Arm hwcap2 is only 32 bits (because the ELF format makes these fields be the size of "long" in the ABI), but since it shares the prototype declaration for get_elf_hwcap2() it is easier to also expand it to 64 bits. The only hwcap fields we implement already that are affected by this are the HBC and MOPS ones, neither of which were implemented in a previous release, so this doesn't need backporting to older stable branches.
