libvixl: fix 64bit constants usage

Since commit 999b53ec8794f203964db3ecf939a3da5c4bc843:

    disas: Implement disassembly output for A64

    Use libvixl to implement disassembly output in debug
    logs for A64, for use with both AArch64 hosts and targets.

disas/libvixl/ contains functions which uses 64bit constants
without using appropriate suffixes, which fails on 32bits.

Fix this by using ULL suffix.
