systemd: support systemd-boot as a stand-alone EFI bootloader
The "systemd-boot" is gummiboot now included into systemd project. The old gummiboot project supported in OE is dead. Our intention is to get a gummiboot-like EFI bootloader without much dependency on systemd and its features. This work is largely derived from the existing bbclass and recipes of gummiboot and systemd. (commit tip: ee25d0e3987d7732a2e46e1640693b4cf419a9fc) Please refer to the history up to the tip for authorship and credit information for the original works. To enable the systemd-boot in build, add this line EFI_PROVIDER = "systemd-boot" in your machine conf file.
