    Use pulongest in aarch64-linux-tdep.c
    
    While testing a patch on the buildbot, I got this error:
    
    ../../binutils-gdb/gdb/aarch64-linux-tdep.c: In function uint64_t aarch64_linux_core_read_vq(gdbarch*, bfd*):
    ../../binutils-gdb/gdb/aarch64-linux-tdep.c:285:29: error: format %ld expects argument of type long int, but argument 2 has type uint64_t {aka long long unsigned int} [-Werror=format=]
    
    This patch avoids the problem by using pulongest rather than %ld.
    This seems safe to me because, if aarch64-linux-tdep.c is included in
    the build, then ULONGEST must be a 64-bit type.
