Use "pulongest" on aarch64-tdep.c:aarch64_gdbarch_init

While trying to build GDB on i686, I found the following error:

 In file included from ../../gdb/common/common-defs.h:105,
                  from ../../gdb/defs.h:28,
                  from ../../gdb/aarch64-tdep.c:21:
 ../../gdb/aarch64-tdep.c: In function 'gdbarch* aarch64_gdbarch_init(gdbarch_info, gdbarch_list*)':

       |                                                                long int
       |                                                              %lld

This happens because aarch64-tdep.c:aarch64_gdbarch_init prints a
"uint64_t" variable using "%ld".  This patch fixes the build by using
"pulongest" instead.  As explained in a similar fix (commit
495143533ad95369811391c6e3c6dadd69d7dd67), this should be safe because
if aarch64-tdep.c is included in the build, then ULONGEST must be a
64-bit type.

"vq".
