Preliminary support for systemd-boot bootloader.#23

Conversation
This adds preliminary support for systemd-boot using the kernel-install tool. It's dependent upon systemd pull request #11281 (systemd/systemd#11281) to work properly with initrd files. It's a little ugly because it wipes (to avoid double copying files) it wipes out the ones that genkernel has already copied to /boot, since genkernel copies those in multiple different places in the code. Ideally those would be refactored and delayed until everything had built successfully, but that was a large refactoring, so for now this adds support as is.

@Whissi do you know if this is still needed? |

Well, if we want to support systemd's kernel-install tool, we need this -- at the moment we don't support that tool. But I don't like this patch. Incoming review. |

In addition, documentation (longusage and man page) must be updated.

Can't we just name it "systemd"?

This feels like it's moving bootloader logic into the compile_kernel logic. I'm happy to do that, I just figured you'd want it all stand-alone in its own little area, so that the it doesn't set a precedent for the next bootloader that comes along to start tinkering with the internals too?

You are right. The suggestion was based on genkernel-3, before I decided to touch so much code and create genkernel-4. Now I think we can do it correctly: But before we are able to do that we need to tackle https://bugs.gentoo.org/505810 - i.e. I'll remove install logic from compile_* to genkernel main script. In the main script we will keep something like https://github.com/gentoo/genkernel/blob/v4.0.0_beta4/genkernel#L337, adjusted of course, which will call 1set_bootloader1 when genkernel was called with --install. We will use the case statement currently used to display a warning to decide if we have to call copy_image_with_preserve or not... then, when we finally call set_bootloader, which would call kernel-install in systemd-boot case.
You get my idea?
tl;dr
Before we get back to adding systemd-boot support, I'll have to refactor install logic. :)

Yeah, I think I follow. Just give me a prod on here when it's ready for some reworking. I'm happy to pitch in, but don't want to step on your plans... 5:)
