shim 15.3

Some highlights:

• Support for revocations via the ".sbat" section and SBAT EFI variable
• A new unit test framework and a bunch of unit tests
• No external gnu-efi dependency
• Better CI (with more yet needed)

As usual, please use the shim-15.3.tar.bz2 tarball, rather than the other two archives github automatically produces.
