This is a new upstream version of shim, built for bullseye. This is
needed for better handling of SBAT-based revocations, plus a range of
security updates from upstream.

[ This is very similar to the bookworm update in #1070660 ]

See attached debdiff for the changes. They're not minimal, but in the
case of shim we need to be as close to upstream as possible for the
sake of getting stuff reviewed and signed. The only local patches to
the upstream source now are:

 * to force SBAT updates to revoke older insecure grub binaries
 * to allow for building on arm64 with older toolchain (retained from
   previous bullseye builds)

There are some minor changes to packaging to help with review.

I've tested locally using CI and also by hand on various machines and
all looks good here.

Obviously, once this is accepted and autobuilt I'll need to submit
things for review and signing elsewhere. Then we'll be want
shim-signed updting too.

shim (15.8-1~deb11u1) bullseye; urgency=medium

  * New upstream release fixing more bugs
  * Remove previous patches, no longer needed:
    + Make-sbat_var.S-parse-right-with-buggy-gcc-binutils.patch (now
      upstream)
    + Enable-NX.patch (we don't want NX just yet until the whole boot
      stack is NX-capable)
    + block-grub-sbat3-debian.patch (not needed now upstream grub SBAT
      is 4)
  * Cherry-pick 2 new patches from upstream for grub revocations:
    + 0001-sbat-Add-grub.peimage-2-to-latest-CVE-2024-2312.patch
    + 0002-sbat-Also-bump-latest-for-grub-4-and-to-todays-date.patch
  * Log if the build is nx-compatible or not
  * Force shim to use the latest revocations by default to block some
    older grub / peimage issues. This is:
    "shim,4\ngrub,4\ngrub.peimage,2\n"
  * Install a copy of the Debian CA certificate into /usr/share/shim.
    Closes: #1069054
  * Clean up better after build. Closes: #1046268
