Michael Chang 7ea474c688 cpio: Disable gcc9 -Waddress-of-packed-member

Disable the -Wadress-of-packaed-member diagnostic for the
grub_cpio_find_file function since the result is found to be false
postive. Any pointers to member of the 'struct head hd' is aligned even
if the structure is packed without paddings.
