John Thomson e91344776b ath79: mikrotik: use vmlinuz (zBoot ELF)
- minimal built initramfs: 10MB vmlinux ELF -> 6MB vmlinuz
- ~5 seconds for kernel decompression, which was equivalent to the
  additional time to load the uncompressed ELF from SPI NOR.
- Removes requirement for lzma-loader, which may have been causing some
  image builds to fail to boot on Mikrotik mt7621.
