* removed
- translations-20170427.tar.xz
* grub2.spec
- Make signed grub-tpm.efi specific to x86_64-efi build, the platform
currently shipped with tpm module from upstream codebase
- Add shim_lock to signed grub.efi in x86_64-efi build
- x86_64: linuxefi now depends on linux, both will verify kernel via
shim_lock
- Remove translation tarball and po file hacks as it's been included in
upstream tarball
