    [AArch64][BZ 18648] change greg_t definition in ucontext.h

    This is an ABI breaking change, but

        typedef int greg_t;

    is not a useful definition on aarch64.

    greg_t is usually used for defining gregset_t which is used
    in mcontext_t.  The general registers in mcontext_t can only
    be accessed by target specific code and on aarch64 greg_t
    is not needed for that so this change is not supposed to break
    existing code, just fix the definition.

        [BZ #18648]
        * sysdeps/unix/sysv/linux/aarch64/sys/ucontext.h (greg_t): Change the
        definition to elf_greg_t.

    (Added another BZ entry that was missed in the previous commit).
