aarch64: make HWCAP updates less error prone
Remove unused _DL_HWCAP_LAST definition and move _DL_HWCAP_COUNT where it is needed (dl-procinfo.h always includes dl-procinfo.c). * sysdeps/unix/sysv/linux/aarch64/dl-procinfo.h (_DL_HWCAP_LAST): Remove. (_DL_HWCAP_COUNT): Move to ... * sysdeps/unix/sysv/linux/aarch64/dl-procinfo.c (_DL_HWCAP_COUNT): ... here.
