build-driver: ship ipxe + memtest86+; grml-live: fix NO_ADDONS autode…

…tection

On arm64 we ended up with the following addon behavior:

  [*] Installing boot addons.
  [x] Missing addon file: "ipxe.lkrn"
  [x] Missing addon file: "ipxe.efi"
  [x] Missing addon file: "memtest86+.bin"
  [x] Missing addon file: bsd4grml

And on amd64 we  ended up with the following addon behavior:

  [*] Installing boot addons.
  [x] Missing addon file: "ipxe.lkrn"
  [x] Missing addon file: "ipxe.efi"
  [x] Missing addon file: "memtest86+x64.efi"
  [x] Missing addon file: "memtest86+x64.bin"
  [x] Missing addon file: "memtest86+.bin"
  [x] Missing addon file: bsd4grml

Now by not using the NO_ADDONS autodetection and shipping ipxe on amd64
+ arm64 and memtest86+ on amd64 only (it's not available for arm64), we
get the expected behavior, as in:

On arm64:

  [*] Installing boot addons.
  [x] Missing addon file: "memtest86+.bin"
  [x] Missing addon file: bsd4grml

On amd64:

  [*] Installing boot addons.
  [x] Missing addon file: bsd4grml
