This update for shim fixes the following issues:

- Updated openSUSE signature

- Use vendor-dbx to block old SUSE/openSUSE signkeys (boo#1168994)

+ Add dbx-cert.tar.xz which contains the certificates to block
and a script, generate-vendor-dbx.sh, to generate
vendor-dbx.bin
+ Add vendor-dbx.bin as the vendor dbx to block unwanted keys

- Only check EFI variable copying when Secure Boot is enabled (boo#1173411)

shim-install from packagekitd (boo#1168104)

relative path lookup for file. (boo#1153953)
- Add shim-opensuse-signed.efi, the openSUSE shim-15+git47 binary
(boo#1113225)
