Fix pg_crc32c_armv8_choose.c to build with ancient glibc releases. If you go back as far as the RHEL7 era, <sys/auxv.h> does not provide the HWCAPxxx macros needed with elf_aux_info or getauxval, so you need to get those from the kernel header <asm/hwcap.h> instead. We knew that for the 32-bit case but failed to extrapolate to the 64-bit case. Oversight in commit aac831caf.
