[OE-core] [PATCH] grub2: Disable address-of-packed-member warnings

[Khem Raj]

gcc9 has turned this warning into error when -Werror is used, lets paper
it over by turning it into a warning for now

Fixes
error: taking address of packed member of 'struct head' may result in an unaligned pointer value [-Werror=address-of-packed-member]
