xc: fix segfault in pv domain create if kernel is an invalid image

If libelf calls elf_err() or elf_msg() before elf_set_log() has been
called then it could potentially read an uninitialised log handling
callback function pointer from struct elf_binary. Fix this in libxc by
zeroing the structure before calling elf_init().
