Description of changes:

[1:1.9.12-1]
- Upgrade to 1.9.12.
- Removed EFI warning, since grub has been updated to use multiboot.
- Add patch to revert "Disable GCC9 address-of-packed-member warning"
While it was able to build locally with 'rhpkg local', the brew
build failed, because the compiler on the brew systems did not
recognized the new GCC9 command line flag:
-Wno-address-of-packed-member
