Security update for shim

This update for shim fixes the following issues:

  • Updated openSUSE x86 signature

  • Avoid the error message during linux system boot (boo#1184454)

  • Prevent the build id being added to the binary. That can cause issues with the signature

Update to 15.4 (boo#1182057)

  • Rename the SBAT variable and fix the self-check of SBAT
  • sbat: add more dprint()
  • arm/aa64: Swizzle some sections to make old sbsign happier
  • arm/aa64 targets: put .rel* and .dyn* in .rodata
  • Change the SBAT variable name and enhance the handling of SBAT (boo#1182057)

Update to 15.3 for SBAT support (boo#1182057)

  • Drop gnu-efi from BuildRequires since upstream pull it into the
  • Generate vender-specific SBAT metadata

    • Add dos2unix to BuildRequires since Makefile requires it for vendor SBAT
  • Update dbx-cert.tar.xz and vendor-dbx.bin to block the following sign keys:

    • SLES-UEFI-SIGN-Certificate-2020-07.crt
    • openSUSE-UEFI-SIGN-Certificate-2020-07.crt
  • Check CodeSign in the signer's EKU (boo#1177315)

  • Fixed NULL pointer dereference in AuthenticodeVerify() (boo#1177789, CVE-2019-14584)

  • All newly released openSUSE kernels enable kernel lockdown and signature verification, so there is no need to add the prompt anymore.

  • shim-install: Support changing default shim efi binary in /usr/etc/default/shim and /etc/default/shim (boo#1177315)
