* New upstream release.debian/15+1533136590.3beb971-1

  - debian/patches/second-stage-path: dropped; the default loader path now
    includes an arch suffix.
  - debian/patches/sbsigntool-no-pesign: dropped; no longer needed.
* Drop remaining patches that were not being applied.
* Sync packaging from Ubuntu:
  - debian/copyright: Update upstream source location.
  - debian/control: add a Build-Depends on libelf-dev.
  - Enable arm64 build.
  - debian/patches/fixup_git.patch: don't run git in clean; we're not
    really in a git tree.
  - debian/rules, debian/shim.install: use the upstream install target as
    intended, and move files to the target directory using dh_install.
  - define RELEASE and COMMIT_ID for the snapshot.
  - Set ENABLE_HTTPBOOT to enable the HTTP Boot feature.
  - Update dh_auto_build/dh_auto_clean/dh_auto_install for new upstream
    options: set MAKELEVEL.
  - Define an EFI_ARCH variable, and use that for paths to shim. This
    makes it possible to build a shim for other architectures than amd64.
  - Set EFIDIR=$distro for dh_auto_install; that will let files be installed
    in the "right" final directories, and makes boot.csv for us.
  - Set ENABLE_SHIM_CERT, to keep using ephemeral self-signed certs built
    at compile-time for MokManager and fallback.
  - Set ENABLE_SBSIGN, to use sbsign instead of pesign for signing fallback
    and MokManager.
