disas/libvixl: Fix upstream libvixl compilation issues

Fix various minor issues with upstream libvixl so that it will compile
successfully on the platforms QEMU cares about:
 * remove unused GBytes constant (it clashes with the glib headers)
 * fix suffixes on constants to use 'LL' for 64 bit constants so
   we can compile on 32 bit hosts
