MK_FORTH: Allow removing loader.4th w/ delete-old

[ziaee]

Summary

The lua loader is quite mature, and /boot is getting a bit cluttered.
Allow removing the forth loader with make delete-old if WITHOUT_FORTH
is set, instead of the previous behavior of only removing the doc.

As usual, please be suspicious; I have no idea what I'm doing. I have
been deleting these files for a while, and have tested this as well.
It makes /boot a lot more managable by being viewable with ls in one
window of 80x25. Particularly, I suspect .so is a library so I put that
under make delete-old-libs.

MFC: no, i dont think so since this is a breaking change of behavior

Thanks for looking this over so soon! Why? I figured, if the administrator wants to removing the 4th loader, we should remove the all of it's stuff.

The administrator will still have loader_simp.old and loader_efi.old.

might there appear loader_4th.efi.old ?

I do not know. Back before the Lua loader I did not take any interest in the internals.

We chatted a bit and it's probably fine to remove; it's created as a backup, might as well clean it up if we're nuking the rest of the scripts.

Fix typo, add loader_4th.efi.old. Thanks @kevans and @tsoome!
