ministub: Simplified EFI stub for Linux, based on systemd’s EFI stub

A simplified EFI stub that allows you to bundle a Linux kernel image, initial RAM disk, and command line into a single EFI binary, so that you can sign the image and use it in a user key Secure Boot setup. This is just a simplified version of systemd’s stub.

Rationale: systemd’s usual EFI stub includes the command line, kernel image and RAM disk as separate sections in the PE. I was having random boot failures with that, and so I wondered if the extra sections were causing issues with my laptop’s pretty poor UEFI implementation.
