Also make vmlinuz-virt.efi world readable

JIRA: INTERNAL
Upstream Status: RHEL-only
ARK commit: 231fb53f9cd6b3a678a4b3f9ae6952d99909b8c2

The file is created by dracut, which by default uses 0600, which is reasonable
for initrd images that contain machine-specific info, but is not needed for
packaged initrds which obviously cannot contain any secrets. Adjust the file
mode in the package list.
